Thank you Paul ,

I do believe that to be the case ... it was saved as a mail merge document with the SQL as you pointed out. Thank you for the code solution. I recall last time I did a similar project I had a heck of a time saving the merge document without the SQL for some reason to get the code to work. I am hoping this code will keep that challenge to a minimum.

I noticed in your code you removed '.MainDocumentType = wdNotAMergeDocument'. I assume it's unnecessary in this application?

And, I have just stumbled on the fact that my data source has two columns labelled as 'TYPE', which is one of the SQL criteria. Would this contribute to the problem? I know it's not good but wondering how crippling a problem it will create in the mail merge process.
