How do I write an Applescript to move a Filemaker window

[LaraBethStone]

I have 2 monitors. My primary monitor is on the right. I would like one of my Filemaker files to open in the left-hand screen. I would normally use the FM script step Move/Resize in a script that runs when FM is opened, but that script step only has the option to move the window to the right of the primary screen. FM recommended using an Applescript to move the screen over, but all I can find is information on how to use Applescript to move a Finder window, not an application window. Any suggestions?
