Topic: More Javascript/DOM woes

Realizing my first implementation of a menu was pretty ghetto, I deveided to redo it in CSS and javascript. Here is the test page: http://www.shootpool.info/navtest.shtml Clicking on Rules, BCA Rules, and Tools should all change the submenu below. Which it does, but I'm getting a ton of javascript errors that are very cryptic. Stuff like:

Error: uncaught exception: [Exception... "Component returned failure code: 0x80570015 (NS_ERROR_XPC_CI_RETURNED_FAILURE) [nsIJSCID.createInstance]"  nsresult: "0x80570015 (NS_ERROR_XPC_CI_RETURNED_FAILURE)"  location: "JS frame :: chrome://global/content/bindings/browser.xml :: get_fastFind :: line 242"  data: no]

I have no idea what that means, and what to do with it: For those interested here is my code:

www.shootpool.info/scripts/menu.js and www.shootpool.info/scripts/showRails.jss

Note: Not all the links work yet, and some send you to old pages with the old menu.

Any ideas whats up here?

hmm, apparently IE6 doesn't support the DOM enough to do blankSub.style.display = "none"; is there a more compatible way I can achieve the same effect?

There's no such sections there right now - you have this message, though:

[an error occurred while processing this directive]

Something is wrong server side.
