Simple Tree Menu Errors

[carteray]

1) Script Title: Simple Tree Menu

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex1/navigate1.htm

3) Describe problem: The code causes a javascript error to appear at the bottom of the page. Specifically it say says that
var ultags=document.getElementById(treeid).getElementsByTagName("ul")
is not defined

Thanks for the help with this. I submitted once before but did not receive a response.

Do you get this error in the demo page on DD as well? What browser are you using? This script was tested in IE6 (win), Firefox 1.x (win) and Opera 8 without problems.

I did not see the error in the example and I am using Internet Explorer. Do you know why that specific line is causing the problem?:eek:
