Error when executing a custom module built with ScriptMaker in FileMaker Script

[christian]

I succeeded finally to create a bundle using scriptmaster. Now i tried to execute it in a filemaker file. First astonishing: my module name is "generate swiss qrcode" but the function is "qrBillGetVariable". Why that? is it possible to use a selfmade name? Second: executing throws an error saying "You can only get ScriptMaster variables after evaluating a script, and before setting any new variable. What das this mean? Thanks in advance!
