Hi Lorne ---

Something is going wrong, then. At the simplest level, your Add button Click() code, with table buffering, should look like:

INSERT INTO table (field1,field2) VALUES (mVal1,mVal2)
THISFORM.Refresh()

Maybe your not doing the refresh?

>Changing to Table buffering stopped the error message, but the insert does not happen, so I assume I will have to overwrite to Add button behavior after all.
