What line does this error occur on? I'm guessing it occurs on this line:

if(http.readyState == 4 && http.status  == 200)

Correct?

Please use code tags when posting code.

See if this thread from the archives helps.

Note that to use code tags, you just need to wrap them using the # button, e.g.
[code=javascript]your code here&#91;/code]
