You'd need a field to select value from value list. It can be global (and in any table) for selecting purpose.
Old style script
If [ theField = "A"]
perform script [ "1" ]
Else If [ theField = "B"]
perform script [ "2" ]
... list all values and scripts ....
There is a new way that use fmp:// protocol to perform script, but it is not so stable.
Thank you for your post!
user19752 & johanhedman made great suggestions! I am also going to move this thread from the FileMaker Community Feedback Space, which is specifically for input on the Community itself, to the Discussions Space where you should receive even more views and potentially more advice!
