Hi

im still a bit of a beginner with filemaker

i have been trying to figure this out but need a little help.

I have this function

If
(GetAsDate ( Date1) - GetAsDate (  Date2 )  <  0 ;
Date1 + 28 ;
Date1
)

What i need is to turn it in to a loop

so that 28 is added to Date1 until Date1 is higher than Date2

I have tries and testes let function and loop,

if any one could help

Many Thanks

Meir

1. Filemaker calculations do not loop.

2. Since you have the Advanced version, you can write a custom function. A custom function can be recursive (i.e. it can call itself in a loop).

3. Looping is not required to solve the current problem. Try =

```Let ( [
diff = Date2 - Date1 ;
periods = Ceiling ( diff / 28  )
] ;
Date1 + Case ( diff > 0 ; 28 * periods )
)```

or, if you prefer =

`Date1 + Max ( 28 * Ceiling ( ( Date2 - Date1 )  / 28  ) ; 0 )`

• I have searched the web for a Custom Function that solves this to no avail…  There are many CF’s that “almost” do what I need but nothing as explained below.
OBJECTIVE:
Calculate a DATE x days AFTER a given date skipping weekends AND bank holidays.

GIVEN:
StartDate
NumbOfDays
Result Desired = Date that skips weekends and bank holidays.

Any year’s HOLIDAY dates can be gleaned from pre-existing Custom Function “HolidayListByYear (yearNumber)” written by Jonathan Mickelson at www.briandunning.com (also uses another Custom Function he wrote called “DateByDayOccur”).

Banking holidays should always include:
* When a holiday falls on a Saturday, it is usually observed on the preceding Friday. When the holiday falls on a Sunday, it is usually observed on the following Monday.
New Years Day
Jan 1
Martin Luther King Day
Jan 20
President’s Day
Feb 17
Memorial Day
May 25
Independence Day
July 4
Independence Day (observed)
?
Labor Day
First Monday in September
Columbus Day
Second Monday in October
Veterans Day
Nov 11
Thanksgiving Day
4th Thursday in November
Christmas Eve
December 24
Christmas Day
December 25
New Year’s Eve
December 31

EXPECTED RESULT EXAMPLE 1:
StartDate = 12/30/2020
NumbOfDays = 2
Result would be= 1/3/2021
NOTE: Must skip Dec 31 (New Years Eve/weekend day), Jan 1 (New Years Day/weekend day)

EXPECTED RESULT EXAMPLE 2:
StartDate = 1/15/2021
NumbOfDays = 2
Result would be= 1/20/2021
NOTE: Must skip weekend AND Jan 18, MLK Day

EXPECTED RESULT EXAMPLE 3:
StartDate = 7/2/2021
NumbOfDays = 2
Result would be= 7/7/2021
NOTE: Must skip weekend and July 5 (July 5th is the observed day for Sunday, July 4, 2021)

SPECIAL NOTE:  The custom function must be able to handle year crossovers such as EXAMPLE 1 above (going from 2020 into 2021.)

Greets, and a happy, holiday season to all.
This is one of those "Well, I could swear it _used_ to work..." FMP (PC) problems: I want a script to create a custom-named folder on the desktop (PC) [for exporting data purposes] so I used the following (see attached) Send Event command:
"cmd /c md " & Quote ( Right ( Get ( DesktopPath ) ; Length ( Get ( DesktopPath ) ) -1 ) & "Job Chop-Chop! Backup" )
...in earlier versions of FMP--and if memory serves--it used to work. (See https://fmrift.wordpress.com/2010/02/03/creating-a-folder-from-filemaker-windows/ ). However, when I try to run the script in FMP v17.x the script fails with the following error message in the Script Debugger, "[3] Command is unavailable (for example, wrong operating system or mode)".
So, I'm trying to figure out why the command's failing--could it possibly be it's because I'm using FMP (PC) in VMWare's Fusion PC emulator (v10.1.4, running in OS Mojave) instead of on a "real" PC? Any ideas for a tweak/fix?
Cheers,
Rich

I am attempting to use the following script in a Database:

Set Variable [\$supplierCount; Value: ValueCount ( List ( Suppliers::UUID ) )] Set Variable [\$month; Value: MonthName ( Get ( CurrentDate ) )] Set Variable [\$suppliers; Value: List ( Suppliers::UUID )] Loop Set Variable [\$i; Value: \$i+1] Exit Loop If [\$i > \$supplierCount] New Record/Request Set Field [Month::Month; \$month] Set Field [Month::fk_Supplier; GetValue (\$suppliers ; \$i )] End Loop
When I run it, however, it creates zero New Records within my "Month" database.
I'm not sure what the issue is. My only hunch is that the List function isn't properly creating a List of the "Suppliers::UUID" field, and is causing the ValueCount taken of it to return 0.
Please let me know of any additional information I can provide, and thank you in advance for any assistance you can offer!

My solution is build according to the 'separation model', so I would like to keep control of the local file containing the layout and presentation of the data hosted in the server.
I wonder if I could have a script to control wether the local file gets its structure, layout or scripting modified, so I need a function to control when a change to the file has been made before giving it a version number. When the file gets open only to work with the hosted data it's not a new version.

• Good evening people.  As the title states, I am a complete newbie to FileMaker Pro.  I've done some fairly extensive work with Excel, but this is my first experience with databases.
For now, I'm looking for advice and suggestions.  I promise I will have plenty of "how do I... " questions later, but for now I need to pick a direction to go in with my new project.  I've spent a bunch of hours viewing Intro to FileMaker tutorials on YouTube and I've experimented with creating a couple test databases.  If this is not the correct forum for this question, please let me know.
So, my wife and daughter are heavily involved with riding horses.  I've been drafted into being on the Board of Directors for our state Quarter Horse Association (Quarter Horse is a breed like Thoroughbred or Clydesdale).   The first thing I discovered is that they have NO association membership database of any sort.   What they do have is simply a file folder of applications for members, one folder for each year.  Me being an I.T. geek by trade, I know there is a better way.  I've at least entered the info into a spreadsheet (my specialty) so we have the info electronically to be able to reference current membership status during our shows.
I wish to create a database for the membership, which I've done so far.  It has basic info - name, address, etc.  I have an ID field that automatically increments with each record - seems to be a strong recommendation in the tutorials I watched.  I have a field that combines the first & last name fields which I plan on using for looking up membership info, sending renewals, etc later.  I also have a membership year field and here comes my first question.  When I renew a member for the new year, I want to keep the previous year's record in the database - should I ever want to print a report for 2016 membership in 2019 for instance, I can.  So I figure I need a static member ID field that is separate from the record ID field I already have that can be linked to another database which will hold that member's horse information.   Is it possible to have a field that will increment serially when I add a new member but will copy from the previous year's info when I renew a member for a new year?
I'm looking for any and all suggestions - links to videos that might help - suggestions for a better way of accomplishing my goal, anything at all.   I'm not a programmer so I don't have that background FYI.
Thanks!

Jon
