document null or not an object

Hi there

I'm trying to compile a sliding menu but am running into problems on these lines:

else {
menuObj.top = nextPos
}

The error message reads: Error: menuObj is null or not an object

Here's my code for the menu:

<script type="text/javascript" language="javascript">


</script>

Any help would be greatly appreciated.

thanks

Adam

Hard to tell in isolation but you have

Code:

function toggleMenu(currElem,nextPos) {
if (stdBrowser) {
menuObj = document.getElementById(currElem).style
}
else {
menuObj = eval("document." + currElem)
}

These two do not equate. I would change it to this (you do not need eval for this, in fact I've never seen a case for eval):

Code:

function toggleMenu(currElem,nextPos) {
if (stdBrowser) {
menuObj = document.getElementById(currElem)
}
else {
menuObj = document.all[currElem];
}
//rest of stuff

If you actually do want the style object instead of the object have:

Code:

function toggleMenu(currElem,nextPos) {
if (stdBrowser) {
menuObj = document.getElementById(currElem).style
}
else {
menuObj = document.all[currElem].style;
}
//rest of stuff
