Old Problem New Tricks

[bumba000]

Hi All,
Thanks for reading.
My ZC version is 1.3.8a.

Well I had a problem in the past where coupons created with a custom name would generate an error when they were used during checkout.

The error was this:
Warning: Division by zero in /home/volt12/public_html/includes/modules/order_total/ot_coupon.php on line 367



So I just let ZC create the coupon codes for me now and it has been working.
Now today helping a customer checkout I see it again. This was with a coupon code that ZC created for me so I know that's not the problem. Same error as before.

A little more testing shows that all of my $ or % off coupons do this. The free shipping coupons dont.

Any help would be greatly appreciated as many of these codes get mailed out to customers everyday.

Thank you,
John

Another Test:

Removing $ratioTax = $adjustedTax/$order->info['tax']; from row 367 makes it work again.

Why?

Thanks,
John
