Peter,

The fields are coming from the mainframe as text, bu the text file is being
saved a a Word doc before the mail merge. However, after reading your first
response I attempted the merge with both the Header and the source being text
files and Word is still pop up the choose delimiter box for both header and
source files. I then get the error "Word was unable to open source file"

To anser Ed's question...None of the header field names contain characters
that can be used as a delimiter option.
