On entering bad CC date - blank page

[Avec 0]

As designed, if a customer enters an incorrect credit card number (primarily not enough digits) a java error message box pops up.  However, if the customer enters a bad card exp date (Sept 2014 instead of Sept 2015) It goes to a blank page.  The URL is just mysite.com/checkout_confirmation.php  I have tried to reload the page as well as CC_validation and no change.  It seems as though the script that creates the popup is freaking out.

Is there any purpose in allowing earlier expiration dates to be entered or selected? The whole problem would go away if only current and future months could be selected. Just be careful that you're using an appropriate timezone for generating the list -- for example, it's almost 1400 here (Eastern Standard Time) on November 30, so in about 6 hours people in GMT and east should see December 2014 as the earliest expiration, while people here (and west) would see November 2014 for another 10 hours.

Month and Year are drop downs with all the months and years from current onward.  Where the error would occur would be if the customer intended to enter January 2015 and entered January 2014.

Looking more into it, An incorrect card number (not = 16 digits) results in a java popup, but incorrect date does not.
