I just added thie Credit and Voucher system to my site: http://serendipityandbeyond.com/catalog/index.php and everything works great down to the point of the customer getting to the order confirmation page where I get the error: Fatal error: Call to undefined function: confirmation() in /catalog/checkout_confirmation.php on line 257 I double checked the code and cannot find where I have mis-typed, etc. I love this add-on, so please help! Also, how can you specify one category for EXCLUSION fron discounts? (ie.: Gift Vouchers?) (I tried listing the rest of the categories, but I have well over 100 and it would not take all that I approved of discounts...) Thanks!
