how messages displayed when first open chat conv div ?

i'm assuming message_cycle() supposed display new messages in div every second, suppose problem here...

i'm not confortable :

var box = $("#jd-chat").find("div#2").parents(".jd-user");

a div can't have id starting number, need <div id="chat2"> instead of <div id="2">.

after line add console.log('box found : '+box.length) ; make sure box correctly found in message_cycle.
