>Yes I knew this (as I indicated in my spiel), and that one can set the default value (as I said I now have done), etc. My beef is that I put the checkbox on the form, wrote code to accommodate it, then it went and changed its data type from T/F to 1/0.

Terry,

Change your test to if( !empty(...Value) ) instead of if( ...Value ).
