Showing all records with dates within 30 days
I am very new to FileMaker scripting and everything I try from the help sections are returning errors.
I am working with a course roster list that has course name and the date the roster was created displayed. I would like it to run a script on enter to show only rosters with dates within the last 30 days. We are not using creation dates.
I have tried:
Enter Find Mode 
Insert Calculated Result [Select; Attendance::Date; Get ( CurrentDate ) - 30 & "..." & Get ( Current Date )]
When entering: Get ( CurrentDate ) - 30 & "..." & Get ( Current Date ) I receive an error that it is an invalid get function.
Basically I am just trying to keep the list of rosters from being 300+
Any help is greatly appreciated!
