Mail Merge w/MS Word 2003 fails (worked previously)

My data is in an .XLS file and I did a mail merge successfully several weeks ago.
Now, I want to use the same letter but a different .XLS file in a mail merge. When I used the Mail Merge Help feature on the right side of the page to browse for the file, it directs me to open an .ODC file. I changed the file type in the pull-down menu to .XLS, searched and selected the correct file. Then the software loads a pop-up requesting a enter a Table.
What happened?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You probably have more than one set of data in the new spreadsheet.  Usually they are identified by the tab labels in the spreadsheet (defaults are Sheet1$, Sheet2$, etc., and would be different if you had renamed them in Excel).

Open Excel and confirm which tab of defined table has your desired Mail Merge data & select that one from the Word Mail Merge.
