error on checkout_confirmation.php

[killerwhale65]

hi,

 

When i use a Gift Voucher to pay for an order, and my Gift Voucher balance is enough to cover the entire cost, i get this error:

 

PHP Fatal error: Call to a member function confirmation() on a non-object in /var/www/vhosts/micro-wings.com/httpdocs/checkout_confirmation.php on line 456, referer: http://www.micro-wings.com/checkout_payment.php

 

This does not happen if the value of my voucher is not enough to cover the entire costs of this order.

 

Any ideas?

 

thanks!

 

Matt
