[Done v1.3.9] Linkpoint - problem with coupons in v1.3.8

Has anyone identified the issue?

Since upgrading, have not been able to process a payment via Linkpoint. However, unlike the other issues listed here, we're not using coupons.

The message received after attempting to pay for an order is:

Your card has been declined. Please re-enter your card information, try another card, or contact the store owner for assistance.

The response code information is as follows [store info is masked]:

Any ideas as to what may be causing the issue?

Okay, well it appears that whatever the put together by DrByte works for the Linkpoint issue. Once installed, we were able to process an order.

THANKS!!!**

There is still an issue with this fix, just received error SGS-002301: Invalid subtotal

I did a little testing to replicate the error and found the following:
It works one way and gets this error another, I will explain.

This is using a gift certificate:

Example order:
Item 1: $7.00
Item 2: $8.00
Subtotal: $15.00
Shipping UPS: $6.50
Total: $21.50

** Now if you apply a gift certificate lets say 20.00 to this order, then linkpoint will decline it and give you the above error message.

I do get it to work this way:

If I do this same order and use "pick up" for shipping ($0.00) it goes through with no issues.

I'm using the built in UPS and USPS modules both get declined using a gift certificate. (Coupons work however this issue is for Gift Certificates only)

1. Are you referring to the file posted above, or the one that was updated since it was posted (ie: refer to the notice in large bold red letters)?

2. If you apply this GV fix, do the symptoms change? --> http://www.zen-cart.com/forum/showpost.php?p=483792&postcount=5

I have the lastest updated Linkpoint file, I did not have the GV fix however I did that and re-tested still did not work same error.

Now I have a question should I leave that GV fix commented out or put it back to the original?

Keep the GV fix.

Any more ideas to resolve this issue?
