var rtl_marquee_Contents='<span style="font-family:Comic Sans MS;font-size:12pt;white-space:nowrap;">' + rtl_marquee_Text + '</span>';
rtl_marquee = new xbMarquee('rtl_marquee', '19px', '90%', 6, 100, rtl_marquee_Direction, 'scroll', rtl_marquee_Contents);

I have nothing displaying in the web-part. How can I make this to work?

Answer 1

This is how i was able to do it. Edit html source.
<div align="center"><marquee id='scroll_news4' bgcolor=#ff9966 "><font color="#000000" size="+1" ><strong>Outlook is down! IT is working on it! </strong></font></marquee></div>
<input type='Button' value='Stop' id ='b1' onClick='button_click()';>
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
function button_click()
if(document.getElementById('b1').value=="Start"){
document.getElementById('b1').value="Stop";
document.getElementById('scroll_news4').start();
}else{
document.getElementById('b1').value="Start";
document.getElementById('scroll_news4').stop();
// End -->
</script>
