This is probably easy for those of you who are fluent in APIs and VB, but I am stuck trying to get a macro to run at a workflow state. In short, I have this macro that creates a CODE128 barcode image and places it on my drawing. This works fine. However, what I want is for it to auto-generate when it is opened and saved IF it is in a certain workflow state. Below is my code currently, and I've highlighted in red the part that I'm stuck on. I'm not sure if the IF THEN is written correctly, but for some reason, I can't get the "workflowState = aFile.CurrentState" to work correctly. It says "Object variable or With block variable not set".
Any help would be appreciated!

pic_path = TempPath() & "barcode.emf" ' The path to store the temporary barcode picture on a disk.
