Well Duane was kind enough to re-write it for me, but all and all I think it
was the use of || and && in the code.
It ended up looking like so.
var number = document.forms[0].card_number.value;
var type =
document.forms[0].card_type[document.forms[0].card_type.selectedIndex].value
;
var first_number = number.substring(0,1);
switch (type) {
case "VISA":
if ( parseInt(first_number) != 4){
alert("Invalid Visa Card Number");
return false();
}
break;
case "AMEX":
var first_two_numbers = number.substring(0,2);
if ( parseInt(first_two_numbers) != 34 && parseInt(first_two_numbers) !=
37){
alert("Invalid American Express Card Number");
return false();
}
break;
case "MAST":
var first_two_numbers = number.substring(0,2);
if ( parseInt(first_two_numbers) < 50 || parseInt(first_two_numbers) > 56 ){
alert("Invalid Mastercard Number");
return false();
}
break;
case "DISC":
var first_four_numbers = number.substring(0,4);
if( parseInt(first_four_numbers) != 6011){
alert("Invalid Discover Card Number");
return false();
}
break;
}
