I am trying to create a data table using server-side processing but It seems the post request sent through AJAX has some undefined variables. I am very new to Jquery data tables so any suggestions would be greatly appreciated. I have attached the codes below as well as the errors.

There is nothing immediately obvious there I'm afraid.
Can you use the debugger to give me a trace please - click the Upload button and then let me know what the debug code is.
