You really should notice what is going wrong, what error message you are receiving, what doesn’t work as expected. From this I can see 2 possible things going wrong:

The debugger line, what is that about? Remove it and debug with Firebug in Firefox

data: { userName: "+userName+" }, This always gives ‘+userName+’ as the username, I guess you need the username here? Do it like this: { userName: userName }.
