[stangasm]

I have the following script:\[code\]<script type="text/javascript"> $.getJSON("http://api.twitter.com/1/statuses/user_timeline/koawatea.json?count=1&include_rts=1&callback=?", function(data) { $("#headertweet").html(data[0].text); });</script>\[/code\]It have created a test document that works offline.But this does not work when I put it online (live or on my local XAMPP setup).Can somebody tell me why, please?Here's the CSS:\[code\]#headertwitterbox { width: 200px; height: 100px; background:url(http://i48.tinypic.com/169ruab.jpg) no-repeat; font-family: 'Source Sans Pro', sans-serif; font-size: 7pt;}#headertweet { width: 180px; height: 53px; float:left; margin-left: 10px; margin-top: 6px;}\[/code\]HTML:\[code\]<div id="headertwitterbox" style="float:left;"><div id="headertweet"></div></div>\[/code\]
