OK, I am no filemaker genius, so I, of course, have more questions. I should change all fields from number format to calcuation format? There are about 250 fields. I don't mind that, but whet do you mean by "create a calculation field in the table?" When I go to "define fields" and define it as a calculation, I don't see how I can do this. Sorry! I am sure I sound dumber than I am.
