Works here in both Firfox 3 and IE 8 in either strict or quirks modes in either browser. Also works in strict mode in Opera 10, Chrome 4 and Safari 4 Win. (I didn't test quirks in those browsers.) What browser are you using?

Also if there is other script code and/or markup on the page, either or both of these could be at issue.

The code you do have in your post is non-standard. There is no layer or ilayer. These were (when the script was originally written) to accommodate NS 4. Almost no one uses that any more, and those tags are no longer valid except in quirks mode.

But, as I say, it works in the mentioned browsers even in strict mode, so that shouldn't be a problem, at least not in those browsers.
