chrome blank screen with flex level popup menu

[IlanD]

1) Script Title: Flex Level Popup Menu

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

3) Describe problem: on http:www.ilandanon.com, IE deals very well. chrome uploads it, shows the page for a scond and then blank screen...Chrom developer tools suggest line 112 on popmenu.js : "Uncaught TypeError: Cannot read property 'id' of undefined"
any ideas what can I do to resolve?
