OK, I feel silly. It didn't occur to me that if I set tabs or other formatting in the merge document, those would carry over to the final document; I thought the new document would have just your default formatting. That makes sense, and makes things so much simpler! I have a footer that I want to use also, and now I realize I can just add that into the merge document too.
The data that I sent was not the actual file that I'll be using, just didn't want to send actual personal information, so there shouldn't be any extra rows, but I will check that code out as well. Thank you so much. I've been working so hard to figure out the coding, I wasn't thinking about the basics!
