I suspect you are trying to open a document incorrectly.
Does this help?

What does this mean? "Word could not open data.doc as a data or header source because it is the active merge main document" I have a data document and want to create labels. When I click on Mail Merge it comes up with the helper menu already filled out. The edit buttons get me no place. How can I clear all of this without losing my data and start over again and using my data as a "get data" Help
