Problem with tax calculation on Tax Exempt goods

I'm having a problem when redeeming discount coupons at the checkout.
Most of my goods are Tax Exempt (ie food) and I get this error
"Warning: Division by zero in /home/dalesbut/public_html/store/includes/modules/order_total/ot_coupon.php on line 364" when trying to redeem a coupon.
After I tested redeeming a coupon against taxable goods there is no problem. So I know the problem is with the php code as it throwing up an error because the calculation is trying to divide something by zero.

Is there any way of getting around this?

Help much appreciated.

Try changing the line:

            $ratioTax = $adjustedTax/$order->info['tax'];

to read:

            $ratioTax = (isset($order->info['tax']) && $order->info['tax'] != 0) ? $adjustedTax/$order->info['tax'] : 0;

:clap: Thank you very much - That sorted it

Thanks for the update that this worked for you on the division by zero error on the Discount Coupons ot_coupons ... :smile:
