Received nothing after executing AJAX post function

Please read the WordPress tutorial on using AJAX in plugins (you are basically adding a plugin to your theme if you need to use AJAX). There are two things I see right off the bat that need to be fixed before your proceed. Note what the tutorial says about the global variable ajaxurl. Also make sure you have set up a php function to process the AJAX request, and that you specify that function in the action field of your data. It’s like you’re making a phone call without a phone number; the system doesn’t know where to send the AJAX request for processing.

I’d work on anything the tutorial suggests, but I think those two things are the big ones right now.
