I'm trying to open a filemaker file from within from a script. since variables don't work when opening files I'm trying other options. THe file being opened was just created by a previous script step so therefore doesn't exist at the time of writing the script so I can't define or add the file. Oddly enough the Automatically Open file option after saving doesn't open the file either. Any thoughts?

Like I said earlier, the Send Event will work always and can be fully calculated. Can you post the Send Event syntax you tried before?
