CCV for entire order--getting a warning-please help

[countingsheep]

Using this contrib:
osCommerce: cvv2 for entire order


Error it is producing:
Warning: Missing argument 4 for validate() in /home/thebrush/public_html/retail/includes/classes/cc_validation.php on line 17

Warning: Missing argument 5 for validate() in /home/thebrush/public_html/retail/includes/classes/cc_validation.php on line 17



Can anyone tell me what to look for?
I changed the area here thinking that may be the problem:
before:
function validate($number, $expiry_m, $expiry_y, $cvv, $cr_card_type) {
$this->cc_number = ereg_replace('[^0-9]', '', $number);
after:
function validate($number, $expiry_m, $expiry_y, $cvv2, $cr_card_type) {
$this->cc_number = ereg_replace('[^0-9]', '', $number);



This is the cc_validation.php file

You need to add some changes the cc_validation.php

See this thread:

Thank you again! That worked by changing the line of code to:
function validate($number, $expiry_m, $expiry_y, $cvv="", $cr_card_type="") {
