Zencart 1.3.9h, not upgraded
I have set up my Zencart and I am busy testing before going live.
I set up my store to issue a gift certificate when a new customer registers on the site. When I used that gift certificate, it all worked fine until after payment had been made.
After payment I was redirected back to my store, but instead of getting to "Checkout Success", I am get to "Step 2 of 3 - Payment Information" and there is a red message displayed saying "It appears that the amount you have tried to apply and your Gift Certificate balance do not match. Please try again." This is after the Gift Certificate has been used and payment has been collected for the purchase amount less the amount applied from the gift certificate balance.
To the customer, it looks as if the purchase has been unsuccessful and the shopping cart still contains the items that were purchased. However, Zencart has generated the order.
Obviously this is a problem because the customer knows that payment has been collected already, but the purchase appears unsuccessful. Most customers will not first check if their orders are listed under "My Account" to see if an order has been generated. Is there a setting I need to change to allow customers to use their gift certificates?
Many thanks for your assistance.
