I appreciate the response. Unfortunately the data source is generated by another program which can only come out as a text file. The header is only one row because it should never be seen.

To get it working with just one header row I would use the "Mail Merge Helper" and relink the header. To get that button you need to add it from the list of buttons not available on the ribbon.

The part that is really weird to me is that all of this works in word 2003-2007 format. All i did was click convert. If you use a .doc for the document and header and the text file as the data-source everything should work correctly.

Really sorry I couldn't help you, I'm sure a brain on here can though.

The only work around I can think of at the moment is to have your data source as an excel file with the headers already in place in Row 1 and use the Import Text option on the Data Table, use the wizard for the and tab delimiter and change the type (text, numbers etc) on that wizard in (Destination in Row 2). You could always copy and paste the excel worksheet into an word document if it is necessary for it to be word.
