Problem with ordering

[Lazar]

I've encountered a problem after installed a payment module for my bank.
When confirm an order a customer is redirected to the bank's payment page. If the payment is successful the customer is back to my website.
The shopping cart is empty but there is no new order in admin and email confirmation. Even more, there is no a customer note on the success_page what is the order number.

I really don't know what is wrong and kindly ask for help.

Many thanks.

We'd need to know what payment module you installed, and if it's a custom module written just for you, you'll probably have to ask its author about the problem.

This payment solution is tailored only for the customers of my bank but Zen Cart payment module hasn't been provided.
This solution only includes hosted payment page and few files to be uploaded on the server where payment gateway is, which connect my shopping cart and the payment page.

The rest of work is on me, first of all writing Zen payment module. For this purpose I've exploited Alertpay payment module and tried to adapt it to my needs by changing few things in it.

Now everything run smoothly between my website and hosted payment page except the generating new orders if a payment is successful (I described the problem in my first post).

I can't figure out where the problem is, either in the payment module or in the files given by the bank (I've adjusted them to the payment module).

Now I'm forced to look around the Internet how to solve this because people in the bank are completely useless. I don't have a choice because in my country there is no bank with ready solution for e-commerce platform!
