Jquery :: Can't Load External JSON

I am working on a project where the jquery/design guru was fired and I am trying to pick up the pieces. Long story short, the project offers surveys to visitors. They click on a submit button (really just a css #id that looks like a button)

Code:

This then loads JSON that is generated via PHP during onload.

A sample of the json:

Code:

I load this json upon page load but I have a problem. On the home page, we have many questions and the json needs to be loaded with a MYSQL query (as of now) such as Select choices from questions where ID = 'question_id'

Here's my dilema. Upon button submit, the json is loaded through a function that animates. It works perfectly, but since I cannot pass the question id to the PHP script that creates the MYSQL query, I can't DYNAMICALLY load the JSON after a vote, only the data BEFORE a vote

I try to load it through an external PHP page but it never loads. For instance:

Code:

So I am able to vote upon submission of 'button' upny_sresbtn1 That works just fine. The problem is the JSON of /return_results.php DOES NOT LOAD. Only the json that loads upon onload, not the return_results.php + formData loads. Oddly enough, when I use the same function, above, with another submit form (one with a form and a bunch of select options, it loads the json from return_results properly) :/

It's supposed to load this function (upny_loadRJSON)

Code:

See the bold part? That's the animate function, which is:

Code:

The part that displays the results, before animation, is below:

Code:

The dilema is upny_iniresults.q_cdata is the json loaded upon first visit to the site. I am trying to get it to read the res_json JSON output from the return_results.php which is posted to upon submission. THAT never works. Instead, only the onloaded json loads. The process, from animation/etc DOES work just not for the JSON data I want.
