I am working with FMP 5.5 and I have related parent to child files. In child file, I have a very long script and when in the child file and when executed, works great. However, when I attach it to the preferences-> Document "when Opening File" ->"perform script" it does not perfrom the script! Why would it not perform the script when I open the file?

Many thanks in advance!

Odds are FM has already opened the file because of the relationship to your main file. If a file is opened in response to your main relationship, startup scripts in child are bypassed. You can resolve this in various ways ... mainly, open your child file when you open your main file. Be sure you are on a layout in main which doesn't call the child file then script opening the child. In this way, the child's startup script will execute.

ahhh, yes. That would make since. Sometimes you can't see the forest for the trees!

Thanks again!
