Our ecommerce magento 1.6.2 site uses [url removed, login to view] as the payment gateway. We have our settings set to "authorize only" due to the fact that we want to make sure our products are in stock before we fully charge the customer and capture the payment. Right now, we have to log into [url removed, login to view] to capture the order (charge the customers credit card). If we try to create an invoice and capture the order, we get an error "Invalid amount for capture" (see the attached image).
We'd like to be able to capture the order through the backend of magento when we submit the invoice. Looking at the code, its trying to capture $0 when we click the "submit invoice" button and I dont know how to fix this.
We are looking for a fix on a budget. The winner of this bid must be able to supply us with EXTREMELY DETAILED STEP BY STEP DETAILS on how this problem was solved including which files were added or edited.
P.S. We DO NOT want to "authorize and capture" right away when the customer orders.
