YUI().use("node", "pjax", function(y){

	// Link to appropriate index.html page, based on where user is in the site
	var here = window.location.href;
	var url;
        // Load top-level index page if user is on "/careers/" or "/contact/" pages
	if (here.indexOf("careers") >= 0 || here.indexOf("contact") >= 0) {
		url = "../index.html";
	// "/clients/" sub-directory has its own index page
	} else if (here.indexOf("clients") >= 0) {
		url = "index.html";
	}
	
	// Create pjax link and insert before div#wrapper closes
	var homeLink = y.Node.create('<a href="' + url + '" id="pjax-link" class="yui3-pjax">Load Home Page Content</a>');
	homeLink.appendTo("#wrapper");
	
	var pjax = new y.Pjax({
		// NOTE: Having 'container' parameter only, and linking to "[../]index.html #wrapper", results in 404
		// Load into this page's #wrapper...
		container: "#wrapper",
		// ...only the content within the destination page's #wrapper
		contentSelector: "#wrapper"
	});
	
	// Confirm everything worked
	pjax.on({

			console.log("Success!");

		"error": function(e) {
