DPM - Error -- not AuthorizeNet

[Nyoung]

Hello,

 I am trying to intergrate my site using DPM. When i try to pass in a price via POST or GET i get the following error:

Error -- not AuthorzeNet. Check your MD% Setting.

I have looked around and I could not find any FAQS etc... With this issue.

The page works if i directly go to the payment page, but not if i pass in a price.

Below are Screen Shots of my code/the error:

Payment Code

AuthorizeNetDPM.php is the default setup

Error

 If you could help i would be greatful!

I am passing the amount into the function via post so that shouldnt effect the function being POST or GET

Then you can check the source code and see why you are getting the error.
