Problems with gift certificates in checkout process: partial payments not showing up

[dstudeba]

My client implemented the gift certificate feature in Miva 9. They can issue and redeem gift certificates fine after I followed the steps here: http://www.miva.com/mm9.3_template_changes.html There are a few odd cases that involve the Payment information screen. I am not able to find the template for the payment information screen so I hope someone here can help. Below is the screen that I am having my problems on.




Partial Payment Problem: When partial payment is selected the dropdown doesn't populate with payment options.

Redeem gift certificate problem: If a valid or an invalid gift certificate is entered it goes to a failure page with this message.

Fatal error:

You will need to assign the paymentmethods item to OPAY. This will allow the Payment drop down to populate.

The error you're getting is because the if you have a form on OPAY you need to pass the payment method.

Add this to your Gift Certificate Form:

<input type="hidden" name="PaymentMethod" value="&mvte:global:PaymentMethod;" />

Brennan, where is this "Gift Certificate Form?"

On OPAY there is a form on the page for the Gift Certificate. Look for a hidden input with an action of RDGC. This will be the Gift Certificate Form.

I believe the OSEL page comes before the OPAY page and in my store, there is no place for the customer to select the payment method of "Gift Certificate"
Although I added all the template changes, it just will not show up.
Any help?

edit: I found that you need to install the module under payment types called customer credit!
That got the payment type onto the OSEL page.

Now when trying to partial pay with a gift certificate, you get a drop-down on the OPAY page that allows the customer to select the secondary payment type. There are no options there !
