Passing values between FileMaker and AppleScript can be a pain. Sure, you can use a named field and table in FileMaker to do this, but if you (or someone else) ever changes either of the names your AppleScript routine breaks. So, even though its not the most efficient way to do things, for short routines I often prefer to use FIleMaker’s ability to run a "Calculated AppleScript" (i.e., compile and run a script from a calculated text).

Other than efficiency, one problem with this approach is that you need to convert data into an AppleScript expression. This custom function makes it a simple task to pass a values list from FileMaker to an AppleScript subroutine:

If you’re working with data from outside of FileMaker, you’ll commonly have to work with dates that FileMaker’s GetAsDate function won’t understand. To handle this, I created a custom function that allows conversion of a wide variety of date formats.

Some examples of how the function works:
