The macro works when run from within the whateveritscalled=AltF11 environment. But the workflow is still broken. The filename and filetype changes do not occur on clicking the save icon.
While I understand the code I am looking at (or at least it makes sense). I don't get how or when it gets invoked or even how to make that happen on my say so.

From the XXX.dotm, when I open (double click) it to a document1.docx, this macro should be invoked upon clicking the Save icon, which would perform the filetype and filename and location changes, this part doesn't work... and I am completely clueless how to even begin looking at it.

The macro works, the invocation doesn't. I am not looking to be provided with the solution but rather guidance on where/how to find the answers.

Your thoughts please.
