I have the following script in which I am validating a CC# but it always pops up the prompt even if the first digit is 4, can someone see my error? var type = target.card_type[target.card_type.selectedIndex].value; var number = target.card_number.value; var first_number = number.substring(0,1); if ( type == 'VISA' && first_number != 4){ alert("Invalid Card Number"); return false(); } <CF_SIGNATURE NAME="Douglas L.
