Fm 12.

I’m trying to create a script that finds a range of records over a 30 day period. However, it gives the error “find criteria not valid”

Enter Browse Mode

Set Variable [ $EndDate; Value:Get(CurrentDate) ]

Set Variable [ $StartDate; Value:Get(CurrentDate)-30 ]

Go to Layout [ “Last 30 records” (Primary) ]

Perform Find [ Specified Find Requests: Find Records; Criteria: Primary::Date: “$EndDate&"..."&$StartDate” ] [ Restore ]

Any suggestions?

Try this instead:

Set Variable $StartDate; date(month($endDate);Day($endDate)-30;Year($enddate))

Set Variable $range; $StartState & "..." & $EndDate

Perform Find <-use $range in the query

Or even:

Set Variable [ $startDate ; Get ( CurrentDate ) - 30 ] 

For some reason, I've always felt more comfortable about explicitly subtracting the day from the day element of the date constructor. 

Well, I deleted my response because I saw that John had that originally.

It would be simpler if it was just a single variable:

Set Variable [ $range ; Get ( CurrentDate ) - 30 & ".." & Get ( CurrentDate ) ]

I find removing days from a straight date the simplest rather than using Day ( $date ) - 30.

Actually, I should clarify further ... you aren't just using Day ( $date ) - 30 ... you are wrapping with the Date() function ... this all requires additional, needless evaluation and I don't find it clearer - on the contrary, it adds needless clutter.  Let's compare:

Date ( Month ( theDate ) ; Day ( theDate ) - 30 ; Year ( theDate ) )

theDate - 30

theDate - 30

I am not sure which one of these requires more evaluations. But certainly the difference - if any - is negligible, and the shorter variation is much clearer.

You might find this discussion helpful for the future Date Ranges that has a link to a Custom Function and here is a file I made up.

Ok, I found that using a range variable in the perfrom find step worked. Now I would like to filter a portal so that it diplays the records for dates in the last 30 days.

Try:

Get ( CurrentDate ) - 30 ≤ PortalTO::Datefield

This is assuming you have no future dates (or that you want to show future dates, if you have them).
