The macro is document-specific; it is only designed to work in the mailmerge main document described in post #1. That is why I said you should add the macro to that document; adding it to Word's Normal template, for example, would cause it to run on other mailmerges as well. Running the macro on another mailmerge main document will produce an error if the tables in it don't have at least two columns and, even then, may not produce the desired result.
