Re: OT Quick JS ?

[Dave Carabetta]

I don't know if this will solve your issue, but I noticed that you have 
"return false();" instead of "return false;" (without the parens). With the 
parens, you are asking JS to return a function called false, whereas without 
them you are returning a value of false.

Just a guess though...

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
