document.getElementById(menu);

[AaronCampbell]

I have a javascript file that I use to place my menus on the page. Part of that is this line:
var menuID = document.getElementById(menu);

Then I use menuID like this:
menuID.style.left = offsetLeft+adjLeft;

The code works perfectly in MS, but in Mozilla FireFox, it gives an error. Is there a way to fix that?

Does Mozilla FireFox support the left property?
It's CSS2 so I doubt it.

Try doing
alert(menuID.style.left)

and see what happens.
