I am not sure my last comment got sent.
The VISA validation works fine by itself, and I believe the problem to be
that it is looking at the rest of the script for the CC validation. I placed
it below for some insight
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' && parseInt(first_number) != 4){
alert("Invalid Card Number");
return false();
}
var first_two_numbers = number.substring(0,2);
if ( type == 'MAST' && 1* parseInt(first_two_numbers) < 50 && 1*
parseInt(first_two_numbers) > 56 ){
alert("Invalid Card Number");
return false();
}
if (type == 'AMEX' && 1* parseInt(first_two_numbers) != 34 || 1*
parseInt(first_two_numbers) != 37){
alert("Invalid Card Number");
return false();
}
var first_four_numbers = number.substring(0,4);
if(type == 'DISC' && 1* parseInt(first_four_numbers) !== 6011){
alert("Invalid Card Number");
return false
