I downloaded a template for 4 to a page postcards. I want each postcard to be personalized, so I added a merge field.

Everything was fine until I hit "Preview", now I keep getting a pop up that reads "You cannot include DATA, NEXT, NEXTIF or SKIPIF fields in comments, headers, footers, footnotes or endnotes".

The merge field is in a text box, but I tried moving the merge field outside of a textbox and I'm still getting the same message.
