Pierre,
To add to what Jim said, you might also want to look at the FSIZE() function which will return the length of the field rather than just the length of the value in the field just to make sure. Assuming the control source is set, try FSIZE(this.controlsource) - this is untested and you may have to strip the table name off the control source. HTH

When the form comes up I would like to see the values for these fields as the are in the table and only execute the gotfocus/lostfocus code when the user tab in and out of these fields.
