Checking for presence of a plugin on opening file
I'm at a loss how to do this.
How do I check that a particular plugin is present when a user opens a file?
I've tried to make a step in a script that will create an error so I can use an if step to deal with it. However even when the plugin isn't installed I can't generate any errors, even though the calculations that depend on the plugin don't evaluate properly and show <function missing> in any calculations.
I'm expecting an error 113 but all I get is 0
The plugin in question is Regex Plugin
I'm using FileMaker Pro 10 Advanced. Mac OS 10.5.7
Any help or pointers would be appreciated.
