Javascript problem, conflicts with my IH4 and Zen Lightbox plugins

[Feznizzle]

Hi,

An attempt to fix a problem with the CSS Click-Show-Hide menu caused a major conflict with IH4 and Zen Lightbox.

Can someone take a look and tell me what I did wrong? Happy to buy you a cup(s) of coffee if you can help me figure this out!

I edited this file:
includes/templates/My_Template/common/tpl_header.php

Just below <div id="headerWrapper"> I added this:

<script>
$(document).ready(function() { 

	// Go to any link that is clicked without waiting.
	$('a').click(function(){
		link = $(this).attr("href");
		window.location = link;
	});

// bc
	catUrl = $('div#navBreadCrumb a:nth-child(2)').attr("href");
	catText = $('div#navBreadCrumb a:nth-child(2)').text();
	//alert(catUrl);
	
	subCatUrl = $('div#navBreadCrumb a:nth-child(3)').attr("href");
	subCatText = $('div#navBreadCrumb a:nth-child(3)').text();
	//alert(subCatUrl);
	
	// last bc item
	lastCrumb = $('div#navBreadCrumb a:last').attr("href");
	
	// main Categories
	$('ul[class=tree-menu] li.top-section-open a.on:first').attr("href", catUrl);
	
	// assign sub menu href
	$('ul[class=tree-menu] li.top-section-open a.on:last').attr("href", lastCrumb);

});
</script>

That fixed my menu and I was super happy... until I discovered that it screwed up my Zen Lightbox. I think maybe there is a better place to put it?

Here is the entire code for my tpl_header.php (before the addition of the script):

I would be deeply grateful to anybody who can spot what I did wrong!
