@redhatlookMay 30.2007 — #I can't help you because i have no idea in which context is used for example [I]this[/I] operator in Slide() function, secondly i can't imagine which object has properties such as height, curHeight etc.

@Mega69May 30.2007 — #Try with this:

<i>
 </i>this.height = document.defaultView.getComputedStyle(obj, null).getPropertyValue("height")

You don't need to use parseInt.

Then, replace this:

window.setTimeout("Slide('"+objId+"').finishup("+this.height+");",finishTime);

with this:

window.setTimeout(function() { new Slide(objId).finishup(this.height); },finishTime);

Obviously, getComputedStyle doesn't work in IE.

@sumeetworkauthorJun 01.2007 — #it does'nt solve anything

m still getting the mesg [B]document.defaultView[/B] and by putting this code the div open/ close in a flash it does'nt scroll anymore.

anyways thanks and suggest if some other script help.
