Worked perfect.  I put the add button in my Row1.  Remerge the form on the entry of the first row and created an unique "Id" field from the index.  It works just the way I wanted.  Thanks a million.

I have created a form with dynamically determined number of rows.  Each row has a dropdown list field that is initially empty.  I want to add the user entry to the list to be used in the field in the rows that follow.
