SetAttribute + IE 6

this script updates an image on a page and resets the class name of a link. Works fine in Mozilla browser. However, the setAttribute method in the second function doesn't work in IE. Is there a known bug connected with this?

Any ideas?

var view;
//update image
function getView(view)
{
var source = view.getAttribute("href");
var imgsrc = document.getElementById("view");
imgsrc.setAttribute("src", source);
setClass(view);
}
// update class names of links
function setClass(view)
{
var arLinks = document.getElementsByTagName("a");
var ct = (arLinks.length-1);
for (var i=0; i<ct; i++)
{
arLinks[i].setAttribute("class", "inactive");
}
view.setAttribute("class", "active");
}
