Using an Excel file as a datasource in a

I have an Excel file with 10 columns (fields). I have to do several differnt mailings from this one spreadsheet. The first two mail merges came out fine, however when I tried the the third using the latter fields, it would only show one field of information (even though I had pulled two fields into the merge). Both fields did have data in them. I tried this on several pc’s and got the same result.
