jaycuz123 Posted April 9, 2008 Share Posted April 9, 2008 I am having a problem with New York Ziptax mod. I followed the instructions and I keep getting this error on my page.

Draeisme Posted May 8, 2008 Share Posted May 8, 2008 Hey, i had the same problem. I fixed it by making a change. The currencies variable has to be defined earlier in the code. Find this code below function calculate() { global $customer_id, $sendto, $ship_zip; Change it to function calculate() { global $currencies, $customer_id, $sendto, $ship_zip; That worked perfectly for me.
