Thanks, but that's confusing me even more. You introduce another term - DocVariables - but I'm not sure if those are the same as document properties or are different beast altogether. I don't understand from your post or your web page how you get info into these whatevers and how you make use of them.

One thing I think I did grasp is that what you suggest would require an add-on. I can't guarantee that all users of the template would have that.

You also mention creating VBA userforms and I don't know what these are either. It's clear you are pitching your answer at a much greater level of technical knowledge than I actually have!
