CCAvenue integration with php

I am new to payment gateways. I would like to integrate CCAvenue into my website using PHP. I downloaded their Intergration kit, included my seller ID and working key, activated my account, and tried to perform a dummy transaction in the index file that they provided on my local host.

But when I click the "Submit" button on the form, it leads me to the CCAvenue transaction transaction page without an error code and error description.

Please let me know where I am making a mistake and what else I need to do.

I would be happy if someone pointed me to a tutorial other than the CCAvenue Integration Guide.
