Error processing cc transaction with authorize.net

[keithck73]

Hello,

I am using Zen Cart 1.3.8a and have a merchant and gateway account with Authorize.net. Both authorize.net and Zen Cart are in test mode. I am testing and after I enter in my credit card info I get back to my site and I see this error:

"There has been an error processing your credit card. Please try again.

Your billing address is shown to the left. The billing address should match the address on your credit card statement. You can change the billing address by clicking the Change Address button."

The billing address is correct.

I also notice in my Zen admin area under Modules->Payment, it says:

Authorize.net (SIM) (Not Configured)

But I did enable this and added the Login and Transaction keys from Auth.net.

Any ideas why this isn't working for me?

Here's the site:
