Hi,

Can I reverse this function:

If(IsEmpty(field1);"X";"")

so that if the field is not empty (has something in it) an X is marked in a corresponding field!

Cheers,

If ( not IsEmpty ( field1 ) ; "X" )

Note that the default empty result is redundant in both versions.

Wouldn't you prefer to display the result as a checkbox, instead of "X"?

You could also have reversed the result inside the If statement:

If( IsEmpty( field1 ) ; "" ; "X" )

ahhh - nice one - you mean a tick instead of a check?

Hi,

Following on from my previous post,

How can I check if a specific date exists in a field, if it does then put a "X" in a corresponding field?

Cheers.

I mean a single checkbox that's either checked or not. For this, you need to define a value list, with a single custom value of 1. Set your calculation field to return a Number result, and change the formula to:

not IsEmpty ( field1 )

On the layout, format the field as a checkbox, using your new value list. Set the font color to the color of your background, and/or make the field narrow enough to show only the single checkbox.

See here for more fun with displaying Boolean (0/1) fields.

How can I check if a specific date exists in a field

You could check by:

DateField = Date ( x ; y ; z )

But it is not good practice to hard code data into calculations, and the question is not clear enough to suggest a better way.

Hi,

What I have in the project is as follows,

Imagine a left hand column with titles of photographs/ works of art, then another column titled activity, with drop down value lists of marketing activity, such as "mail shot, email campaign etc" then next to each of these is a start date and an end date.

At the top of the page going from left to right, is a list of dates written as text, and underneath an empty field.

What I am aiming to do, is determine if the date at the top of the page is between the range of the one's selected in the start / end date and if so - to place a "X" or symbol in this empty field.

Hope this makes more sense?

Cheers,

Dan :)

I am afraid you have lost me there. What is the purpose of this?

It's to track marketing activity over a financial year, what we are doing on certain dates.

I will screen grab what I have done so far - and you can see...

Cheers,

You're using FileMaker Pro -- it's a database not a spreadsheet. Databases can do a lot more than spreadsheets.

Perform a find using the date range, and FileMaker will only display those records that match the criteria.
