Desperate ajax help needed

[Lionel]

I am working on a nice hack: Calendar sports predictions

I have my predictions.php where I have all the code laid out for submissions, but it is important to me that the prediction are done in ajax so the user does not leave the page which sometimes has multiple events, thus multiple predictions (for each event).

I sought help in the paid forums, got the run around by 2 wantabe coders so I decided to do it myself, and if not for the ajax, I am pretty much done.

What I am looking for is something in the manner of the Post Thank You hack to submit into a TABLE_PREFIX ."predictions.

That's all I need. As a picture is worth a thousand words, I am attaching two of them, both from calendar custom fields.

Please someone give me the ajax formula. I never worked on ajax before and I have no idea where to start. I need the formula when you click on submit to submit to predictions.php and the one when you click on remove simply deletes the predictions (once it is deleted the boxes reappear, providing that timenow is smaller than dateline_from, all that is done already)
