Arbortext Stylesheet Module Error

[Garvels]

I made a stylesheet that was a copy of an existing, working stylesheet. I copied the modules, and, using the Organize Modules button, I removed the old modules and added in the new copied ones. I made no other changes, saved the stylesheet, and closed it. Then, when I try to re-open the stylesheet, I get the following error:

ERROR: Stylesheet includes module 'Engineering Style Sheet'  (C:\PTC\custom\doctypes\Engineering\Engineering_ditabase.style) multiple times in module hierarchy. The stylesheet module hierarchy may have been invalidated by other stylesheets that are currently open and share common modules with this stylesheet. 

I looked through the modules in Notepad and can't find any reference to my stylesheet in them. I've tried duplicating this stylesheet a few times and keep getting the same error. I was able to successfully duplicate one previously.  Is there anyway I can fix this problem? Or perhaps does somebody know where I'm going wrong?

This is an ancient question, but thought I'd answer for others who stumble across it.

It sounds like you have nested modules. For example:

• The main stylesheet points to module A.
• A points to module C.
• You then added module B to the main stylesheet.
• B also points to C.

To troubleshoot this, you'd have to remove the pointer from A or B (or both) to C.
