Something appears to be very messed up on your site. All pages except your frontpage have duplicated head sections and are not including mootools. For example, look at this grab of the head data from your FAQ page:
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<meta name="robots" content="index, follow" />
<meta name="keywords" content="joomla, Joomla" />
<meta name="title" content="For you" />
<meta name="author" content="" />
<meta name="description" content="Joomla! - the dynamic portal engine and content management system" />
<meta name="generator" content="Joomla! 1.5 - Open Source Content Management" />
<title>For you</title>
<link rel="stylesheet" href="
www.laralahoud.com/barry/plugins/content.../faqslider.css" type="text/css" />
<script type="text/javascript">
window.addEvent('domready', function(){ new Accordion($$('.panel h3.jpane-toggler'), $$('.panel div.jpane-slider'), {onActive: function(toggler, i) { toggler.addClass('jpane-toggler-down'); toggler.removeClass('jpane-toggler'); },onBackground: function(toggler, i) { toggler.addClass('jpane-toggler'); toggler.removeClass('jpane-toggler-down'); },duration: 300,show: -1,opacity: true,alwaysHide: true}); });
</script>

FAQ Slider currently requires mootools and your template is not allowing Joomla/FAQ Slider to load it. This must be a template issue so I would suggest you go to the person who designed your template...
