I put that code in (and made sure to change the URL to bandofhonor.com) although the code looked exactly the same as what I had put in before. We got an error message again, so I reverted back to the page I sent you in post 31. So now it is not accessing checkout_success, although the order IS going through. Still no email from our site though, it is coming from Authorize.net.
New note: my boss asked me to put the pages back to what we had in Post #23... before I put in the code you gave me. Essentially square one.
