You have to show relevant code, especially because english is not your first language. Helps with any misunderstandings. Also, not knowing english is no excuse for not capitalizing letters and adding punctuation.

My guess (and it is a guess) is that in one javascript method you're trying to access ctl09 and it doesn't exists because (if you look at page source) it is called ctl00_pnl01_ctl09 or something like that (server side controls get their names mangled so they are unique on the page). You can access corrent name in javascript like this: <%=ctl.ClientId %>
