Hey,

I'm pretty new to this API stuff (Just started last week) and I've been trying to update an API so it does the following:

1. If I run the macro when a Part or Assembly is open, it will bring up a window that promps the user to input a set of data (ie, project, finish, vendor, etc.)

2. If I run the macro when a Drawing is open, it will bring up a different window that propmps the user for different data (ie, Checker, Manufacturing Approval, etc.)

So far, I have it working perfectly for Parts and Assemblies.  But when I run it with a Drawing open, I get "Run-time Error '91': Object variable or With block variable not set" and it hangs up on this line: Prop = CurrentDoc.AddCustomInfo3(CurrentDoc.IGetActiveConfiguration.name, PropName(0), swCustomInfoText, " ")

I have double checked all my parameters and cannot seem to find one that is not set.  Does anyone know what's wrong?

Current API attached.

Thanks,

Tara
