Auto message box on open (when using template)

[Drizz]

Help friends...

I figured out how to create a macro to have an informational message box pop up when you open up my word doc, however this particular doc is a template, and so it only works when you right click and choose open, vs if you were to double click to open up the actual template like normal, of which I have multiple boxes pop up to automatically fill in fields throughout the document. (Probably confusing)...

So my question is, how do I get an auto message to pop up on a template document BEFORE the auto field questions come up on a normal double click to open the doc?
