Authorize.net not supported

[bmlbytes]

I have set up the FreeCart to work on my website. And I must say I LOVE how easy it is to integrate. However, when I try to link it to Authorize.net when a person clicks the Pay button I get this:

The following errors have occurred.
(92) The gateway no longer supports the requested method of integration.

This happened when I used this code for the pay button:

Code: Select all

   <FORM ACTION="https://secure.authorize.net/gateway/transact.dll" METHOD="POST">   
      <SCRIPT>
         CheckoutCart();
      </SCRIPT>
   <INPUT TYPE=HIDDEN NAME="x_Login" VALUE="xxxxxxxxxxxx">
   <INPUT type=submit value="Proceed to payment">
   </FORM>   


I saw a fix for it on the forums here, but it was in Perl and I don't think Perl is working properly on my server (I've tried several Perl scripts in the past, and when I ask for support from the hosting company, they just say the code is wrong).

I think Authorize.net requires it be changed into MD5 encrypted information.

I hope someone can help me with this. This is the only shopping cart that we have found to really work with our site, and I hope I can actually use it with Authorize.net

Sorry guys for the post. I figured it out. I basically updated all the PHP code to work in PHP5, then I used a function built into PHP5 to do what the mhash function would do normally.
