kfq61 I recommend first of all that you ensure the Excel database is constructed properly and that proper headings are in place.
Headings must be without spaces ie HomeAddress etc.
When you are happy select ALL in Excel Copy
open WORD and paste into it.
Save the WORD document as New Database or anything.
Again make sure the headings make sense and have no spaces.
With your new Database saved and still open
make sure you have the Database toolbar available.
If not right click on a grey part of plain toolbar and select it,
Now click on the little icon on the database toolbar that looks like a small pen.
Now review your database item by item to ensure it all makes sense. Now try the Mail Merge again.
