Arghh! undefined null or not an object

I am using hideAllExcept.js from

http://enure.net/dev/hide-all-except-one/

I have everything working perfectly locally & when uploaded. However when it is included on a page with other scripts I get the “undefined null or not an object” error and the hidden divs are stacked below the div that is supposed to be visible.

Is this possibly a conflict that jQuery.noConflict(); would solve? Or is this a race condition where other scripts are loading first and even though jQuery uses $(document).ready(function() { the content of the hidden divs is loading before the function can hide them?

post link or source

Edited to add. Looks like the problem may be prototype.js. I implemented jQuerynoConflict in hideAllExcept.js. I’m used to jQuery breaking prototype and not vice versa.

The hidden divs unfortuantely do show briefly stacked below the visible div. I had this same issue with hidden content in <li>s showing stacked on pages with multiple scripts until scripts load with jCarousel. Dynamically loaded content did not do it.
