Working perfectly...kinda.

Hey gang

I've set up zen cart for a retail client and everything seems to be in woiking order.

I've set up a Visa card and a $0.05 testing product to ensure proper operation. Transactions go through without a hitch, including "Thank you" message and transction comfirmation email.

The problem is that no funds have been deducted from the Visa Card. Did I forget something?

Help is very much appreciated.

If you're using the built-in "offline credit card" module, then all it did was collect your CC number.
If you want to process credit cards live, you'll need to subscribe to a merchant account service tied to your bank account, and then configure the appropriate payment module in your store to work with the gateway service you subscribed to.
