I didn't see javascript forum, so I just ask my question here, if you don't mind.
I have been trying to figure out why I am having the following error:
top.body_frame.left_frame' is null or not an object
Please take a look at my code and tell me what I am doing wrong.
Thanks in advance

initMouseEvents();
if (is.ie){
document.all.square.style.top = "0px";
}
if (is.ns5){
d = document.getElementById("square");
d.style.top = 0;
