Not to be critical, but your english is a bit rough to follow.
I would suggest posting, at least, the parts of your code that are relevant to your problem (use the
[/CODE ] tags for easy reading). Code is language neutral and most here may be able to understand your problem better just by reading the code.
Also your talking about an AJAX problem. These kinds of problems are a bit more difficult to diagnose, so make your questions more detailed. Multiple sentence explanations are a good thing. Remember we haven't the slightest idea what your trying to do. And even if we did there is variety of ways to approach almost any project. So any detail you leave out of your questions can lead to poor answers.
