Fatal error: Call to undefined function AuthNet_Result()

I added the Payment Reponse option for Authorize.net AIM and the following is the response I get after running a transaction though:

Fatal error: Call to undefined function AuthNet_Result() in /home/thafro/public_html/checkout_failure.php on line 91

It doesn't look like I am getting a AuthNet result code so is the checkout failure do to an error on my eCart pages?

I have attached the checkout, checkout failure and confirm php pages to see if you could check the code and offer any assistance.

you're not getting any results from authorize.net because of that error. the function AuthNet_Result() returns the results you are trying to see.

that function is defined in the WA_eCart/Adv_CO_Scripts/AuthNet_PHP.php file. make sure that file has been uploaded to the server.

Jason, I made sure the AuthNet_PHP.php file was uploaded to my server but I still get the same result. I have that file attached here in case you could take a look at it.

Do you have any other suggestion?

Jason - Does the AuthNet problem I am having require a Premier tech support ticket? I can do that today if you think that would be best.

no, a premiere ticket wont be required, but i'll need to take a look at in directly:

I have created a support ticket so we can look into this issue further.
