Have a problem with javascript functions in handling an accordion

Hey everyone, please i’d have this issue, i have this accordion which i use it in drupal, the problem is that it opens the first 10 tabs and not the other ones, here is the code which i think needs some work:

function wysiwyg_tools_plus_theme_toggleAccordionContent(eventId) {
eventId = eventId.substring(eventId.length-1, eventId.length);
$(‘#acc-’ + eventId).toggle(‘fast’);

In this example it opens only the first 10 items of accordion
When i change it into :

function wysiwyg_tools_plus_theme_toggleAccordionContent(eventId) {
eventId = eventId.substring(eventId.length-2, eventId.length);
$(‘#acc-’ + eventId).toggle(‘fast’);

it now opens only the 10 second items of the accordion:

Here is where i’ve implemented it: http://www.plus-demo.info/drupal/biznesi-rrjeti-zona-plus

Please help me with this…

the whole code is :

(function ($){

Drupal.behaviors.wysiwyg_tools_plus_theme_createTabs = {
	attach:function (context) {
		//tabbed elements first
		// for each of the div's apply an id to each
		$('.ready-tabber', context).each(function (index) {

			// a couple of opening set-ups for first run.
			if (index == 0) {
				//create the ul that our headers can be added to for the tabs row plus id's to link to content
				$(this).before('<ul class="ready-tabs"></ul>');
			}
			// add an indexed id to the div
			$(this).attr('id', 'content-' + index);

			//wrap the tab header as an anchor and li
			$(this).children('.ready-tabber-header').wrap('<li class="ready-tab"><a id="tab-' + index + '" href="javascript:void(0);"></a></li>');

			// move the header element to the ul as a li
			$(this).children('li').appendTo('ul.ready-tabs');
		});
		$('.ready-tabs', context).after('<br clear="all" />');
	}
}

Drupal.behaviors.wysiwyg_tools_plus_theme_createAccordions = {
	attach:function (context) {
		$('.ready-accordion').each(function (index) {
			$(this).attr('id', 'acc-' + index);
			$(this).children('.ready-accordion-header').wrap('<a class="acc-head" id="acc-head-' + index + '" href="javascript:void(0);"></a>');
			$(this).children('a').insertBefore(jQuery(this));

    // awful hack: apply .last to the accordion heads which appear to be last
    if ($(this).next().length == 0 || !$(this).next().hasClass("ready-accordion")) {
      $(this).prev().addClass("last");
    }
		});

	}
}

Drupal.behaviors.wysiwyg_tools_plus_theme_initPage = {
	attach:function (context) {
		$('.ready-accordion', context).hide();
		$('.acc-head', context).children('span').addClass('collapsed');
		// set the click events
		$('.ready-tabs a', context).click(function (event) {
			idClicked = this.id;
			wysiwyg_tools_plus_theme_toggleTabContent(idClicked);
		});

		$('.acc-head', context).click(function (event) {
			idClicked = this.id;
			wysiwyg_tools_plus_theme_toggleAccordionContent(idClicked);

    // attach an active class to active accordion heads
    if ($(this).children('span').hasClass("expanded")) {
      $(this).children('span').removeClass("expanded");
				$(this).children('span').addClass("collapsed");
    } else {
      $(this).children('span').addClass("expanded");
				$(this).children('span').removeClass("collapsed");
    }

		});
		wysiwyg_tools_plus_theme_toggleTabContent('tab-0');
	}
}	

/**
 * Toggle the visibility of the tab content and set active link
 */
function wysiwyg_tools_plus_theme_toggleTabContent (eventId) {
	eventId = eventId.substring(eventId.length-1, eventId.length);
	$('.ready-tabber').each(function (index) {
		if (this.id == "content-" + eventId) {
			// set the link as active
			$('.ready-tabs #tab-' + eventId).parent('li').addClass('active');
			// expose active content
			$(this).show();
		}
		else {
			//unset active class from non-event links
			$('.ready-tabs #tab-' + index).parent('li').removeClass('active');
			//hide unactive content
			$(this).hide();
		}
	});
}

/**

function wysiwyg_tools_plus_theme_toggleAccordionContent(eventId) {
