Supertrapp Store is broken

I ordered some stuff from the Supertrapp Store, but when I check out I got the following errors:

Warning: reset() [function.reset]: Passed variable is not an array or object in /home/supershop/public_html/includes/modules/order_total/ot_tax.php on line 38

Warning: Variable passed to each() is not an array or object in /home/supershop/public_html/includes/modules/order_total/ot_tax.php on line 39
