Using AppleScript to perform find

[darrenN]

I'm trying to perform a find using applescript I want to find records from 30 days from todays date. I've got the following:

on findOlderthan30(findType)

ignoring application responses

if findType = "Show" then

tell application "FileMaker Pro"

activate

show (every record of database 1 whose cell "deudate" = "Today - 30")

end tell

end if

end findOlderthan30

Today is ment to be todays date minus 30
