Try adding 100000 to the mergefield using the following calculation field
construction

{ = (100000 + { MERGEFIELD [Access Field] }) \# "0000000" }

I am merging from an Access database query. One of my fields is a 7 digit
number that always begins with '05'. Is it possible to change this within
word so that it is prefixed with '06' instead, with out changing it in
Access? so instead of saying 0512345 it would say 0612345

thanks
