OK, I think part of the problem is that VFP only gives you a DataSet with one Table. However, you can either pre-define your DataSet with an additional table, or add a Table to your DataSet once you get it from the WS and if I were you, I'd add a Speaker Table so that for each row in your main table (for each meeting), you'll add one to three rows in the new Speaker table.
