MSWord 2003 Conversion from 2000

Our office is converting from Windows 2000, V5.00.2195, SP4/MS Office 2000 to Windows XP Pro, V2002, SP2/MS Office 2003 Pro.

The problem I'm having is this: we've created 100s of merge documents with Excel datasources, which link via DDE commands to ODBC datasources for the information. In MSOffice 2000, the Word document opens then the Excel datasource opens in another window. In the Excel datasource the users can type an ID number in a designated field and get just the one record to show up for merging. Then they return to the Word document and merge the record and print.

With MSOffice 2003, the Excel datasource doesn't open to allow entry of the ID field and it looks like the datasource has to return all records to begin with, then you can filter from there.:sigh:

Is there not a way to set up parameters such as the ID field when opening the merge document to begin with so that all records don't have to be returned up front?
