Hi guys

Site is http://shop.chemicalresearchers.com/zencart/
Version: Zencart 1.3.9f

I have installed the alert pay payment module: http://www.zen-cart.com/index.php?ma...roducts_id=227

During checkout, when a user is passed from zencart to the alert pay site, an error message is displayed in the browser, 'ap_shipping charges is not defined'.

I have tried adjusting the shipping settings in the zencart back end, and looked on numerous forums, but I can't find a solution to this.

Any ideas please?

Cheers
