I'm assuming that you are calling this function in the onSubmit action of
the form tag? If so, are you typing "onSubmit="return CCValidate(this);"? I
don't know the name of the function, so obviously replace "CCValidate" with
the function name.
I understand your frustration, as I've been there many times with JS, but I
find it's the little nuances of the language that tend to trip me up. That's
why I'm asking how you're calling the function. Again, I'm assuming it's an
onSubmit action. Is this true? If so, is it typed like I have it above? What
happens?

Well here is what I did. As per Nate's suggestion I put the !== to a != and
still it alerts that the value is not correct. As per Dave suggestion I took
off the () after the return false and it submit the page and does a write of
the word false
Im frustrated, this should be easy, but is proving diffucult
Here is the updated code
var type = target.card_type[target.card_type.selectedIndex].value;
var number = target.card_number.value;
var first_number = number.substring(0,1);
var first_two_numbers = number.substring(0,2);
var first_four_numbers = number.substring(0,4);
if ( type == 'VISA' && parseInt(first_number) != 4){
alert("Invalid Card Number");
return false;
}
if ( type == 'MAST' && 1* parseInt(first_two_numbers) < 50 &&
parseInt(first_two_numbers) > 56 ){
alert("Invalid Card Number");
return false;
}
if (type == 'AMEX' && 1* parseInt(first_two_numbers) != 34 ||
parseInt(first_two_numbers) != 37){
alert("Invalid Card Number");
return false;
}
if(type == 'DISC' && parseInt(first_four_numbers) != 6011){
alert("Invalid Card Number");
return false;
}
