mozilla 1.4 issue – works fine in other browsers..

It toggles a div on and off from a graphic button to create the effect of a pop up window.
I have this in the head:

css:
#popupBox {
position: absolute;
top: 26px;
left: 126px;
border: solid 1px #000000;
visibility:hidden;
height: 307px;
background-image: url(content_images/smlpo.jpg);
width: 231px;
}

javascript:

<script language=”JavaScript” type=”text/JavaScript”>
<!–
function show_popup(){
document.all.popupBox.style.visibility = “visible”;
}

function hide_popup(){
document.all.popupBox.style.visibility = “hidden”;
}

function toggle_popup(){
if (document.all.popupBox.style.visibility == “visible”)
hide_popup();
else show_popup();
}
//–>
</script>

and in the body:

<a href=”javascript://” onClick=”toggle_popup()””>

mozilla’s debugger is telling me there’s an issue with ‘document.all.’ but I can’t figure out what’s tripping it up.

Any clues gratefully appreciated!

thx

Also in #JavaScript _↴
