I just upgraded to Office 2003 Professional and I can't
create a mail merge document using a query with
parameters.  When I go to the "Select Data Source" part
of the mail merge helper the queries with parameters
don't show up as a choice. I tried deleting the
parameters, then selecting the query, save the document,
and then add the parameter to the query, but the I get an
error message "This operation cannot be completed because
of dialog or database engine failures. Please try again".
I created documents with Office 2000 using queries with
parameters and it worked OK.  
Any ideas?
