I have a requirement where my registered users will enter a membership No i need to look up their amount due and provide a pay button. If they decide to pay i will need to redirect them to payment gateway and complete the payment and then i need to receive the approval or failure from the payment gateway and then reduce the amount paid by the members and update the list back.

I know how to create columns for Mem# & amount due using F & L module.

But next step is integration of Payment gateway

and the next step is to reduce the amount paid by the member and update the amount due.

Just wondering if anyone has done this.

Thanks
