Question : (ajaxobject).readyState at zero?

I'm trying to use ajax techniques to post information to a database and then reload the contents of a div using the new information. The javascript call to launch the php script works (.open('POST',url,true)), and the information correctly posts into the database. The .responseText, however, is never generated. Upon further testing, it seems that the status and readyState of the connection object never get past 0.

Attached is the code. In this example, stateChanged is called (bizarre) as the first alert() is called, but the inner alert() is never called. That is, the if statement is never satisfied.

Any help would be greatly appreciated!

Answer : (ajaxobject).readyState at zero?

change:
xmlHttp.onreadystatechange = stateChanged('entry_'+repairid);

to:
xmlHttp.onreadystatechange = function(){ stateChanged('entry_'+repairid); };
