I get an error (Object doesn't support this property or method) on 56. In Internet Explorer and I would like to try to keep it cross browser compatible.
This is the source of the function:
SM.Util.prototype.constructor.Notify = function(txt) {
chat = document.getElementById('chat'); //this is line 56 and chat is a img
notify = document.getElementById('notify');
notify.style.left = leftValue;
notify.style.visibility = "visible";
notify.innerHTML = txt;
setTimeout("SM.Util.Notify.Clear()",5000);
}
