Jill,

Change your return statements to say "RETURN 0". This way, it won't let your user out of the text box until a non-zero value is entered, and it will reset the value of the textbox to 0

At times, once the form is diaplayed, and the user user clicks on a combo box on the form, the valid does not fire, i.e., the focus leaves the textbox and goes to the combo box. [If the user presses the TAB or ENTER key with the intial zero value, the appropriate error message is displayed.]
