Is EventScript working in the separation model ?
Sure EventScript can work inside a multi-files solution. Depending on the relationships you have between your files, a requirement to trigger scripts which are physically placed in another Filemaker file, will be to open this distant file before using these triggers. So make sure you are running an opening (startup) script to open your target file(s) and the EventScript triggers will work perfectly, even if the trigger is inside the “file 1” and the script to run is into the “file 2”. The distant files can be opened in hidden mode. About the plug-in’s call, do not forget the 1st parameter is the name of the file where the script to run is placed.
