Sys.ArgumentException: Sys.ArgumentException: Please set valid values for the height and width attributes in the slider's CSS classes Parameter name: element size

Hi, 

Guys I am stuck with this problem. I am creating dynamic extented sliders from code behind. And I am getting following error list, you can view it here : https://skydrive.live.com/redir?resid=4CFD9A87074E190C!1037&authkey=!AHw68oWfM08AzO4

In result of these I am unable to move the slider's handle in FireFox and Chrome but its works perfectly fine in IE and also it doesn't give errors in IE. 

This is the script that Ajax is generating: 

ys.Application.add_init(function() {
$create(Sys.Extended.UI.SliderBehavior, {"BoundControlID":"ctl00_ContentPlaceHolder1_gridRatings_ctl05_txtBoundCompetency37814","Maximum":5,"Minimum":1,"id":"ctl00_ContentPlaceHolder1_gridRatings_ctl05_seHBP37814"}, null, null, $get("ctl00_ContentPlaceHolder1_gridRatings_ctl05_txtCompetency37814"));
});

I think its thoes null values giving me error. Any help is much appriciated. 

Thanks,

Attiqe
