checkout error message please help

[judoka]

Hi I was wonder if someone could please help me with this problem. I need to get this resolve so that I can go live. I just uploaded my website up to my host and now I am having the following problem. When I try to make a test purchase and I click on continue to go to the payment information screen all I get is a blank screen. In my cpanel I get the following error message:

PHP Fatal error: Call to undefined function: javascript_validation() in /home2/giftttny/public_html/catalog/includes/classes/payment.php on line 82

When I look at my payment.php file this is line 82

$js .= $GLOBALS[$class]->javascript_validation();

I'm not 100% sure where I need to go to check on this validation but I have look in all the usual place, english.php, configure.php etc. but not really knowing what I am looking for, I'm really just kind of shooting in the dark hoping that something will just pop out at me. I've search in the forum hoping to find something but no luck. I have even cut and paste most of the above file from my local machine to the live host file hoping to fix the problem but no luck there either. But the funny thing is that everything is working ok on my local machine
Could someone please help me figure this one out?
Thank you for any and all help.
Jose

This was resolved, it was due to a misbehaving payment module. Disabled the module, the error goes bye-bye!

Thank you Msasek I found that the problem was beening cause by the Free Shipping module. I disable it until I can figure out why it is causing the problem.
