Error with coupon and GV

I got this error after entering a discount coupon and Gift Certificate at the same time. What give?

on line ```
Warning: Division by zero in /home/alifina/public_html/boutique/includes/modules/order_total/ot_coupon.php364

I cannot reproduce this error ...

What version of Zen Cart are you using?

Clean install or an Upgrade?

How did you install? How did you Upgrade?

Can you reproduce this error any time?

What add-ons do you have?

I'm going to try this again, but to answer you questions:

version 1.3.8a (upgraded following the upgrade instructions)

I'm going try this again. The order went through fine after the error. This was an order paid via PayPal Express.

I'll update this again shortly.

thanks

Hi to all,
Any updates with this thread? I get the same error when trying to redeem a Discount Coupon.
The version of my zen-cart is also 1.3.8a, the only add on I have is MZMT Ups shipping.
Same thing with my older zen-cart 1.3.4 is working fine (no errors).... this is the complete error I get:

Warning: Division by zero in /var/www/vhosts/mydomain/httpdocs/zen_1_3_8a/includes/modules/order_total/ot_coupon.php on line 364

Is this the same issue?

I also found this post which is in ot_group_pricing.php I am having the issue with ot_coupon.php in line 366, I tried to apply the same solution you suggested with no luck... I added the code in red after line 323 in the ot_coupon.php page (which has the same bit of code there) .. but still get the same error...

Sorry DrByte,

Seems to be working with the same solution, maybe I was having problems with the ftp client and the code I had modified was not being uploaded, after many attempts it is working fine now...
So the suggetion from that thread works out fine

Many thanks!!
