Hi,

I'm trying to add a sales tax rate to Zen Cart. Originally, there was one tax rate (for TN) setup in the store. I was testing it in preparation for changing it on the upcoming no sales tax weekend.

When I went to edit the tax rate the change didn't save. And not only that but no tax rates showed up underneath the tax rate area in the admin section of zen cart.

When I tried adding an entirely new one I received the same result. I fired up phpMyAdmin to look at the table that the tax rates are stored in. I saw the new tax rates I tried to create but each row (in the table) had 0's for every value except the data/time I created the new tax rate. So I tried adding a tax rate manually from within phpMyAdmin. That worked except it doesn't show up in the admin interface or checkout process of zen cart (so really it didn't work).

I've tried replacing just the tax_rates.php in the admin folder with one from a freshly downloaded version of Zen Cart.

Relevant details:
Zen Cart version v1.3.8a

Any help in this matter would be greatly appreciated.

Thanks!
