JQuery plug in suddenly stopped working?

Hi,
My JQuery plug in suddenly stopped working. Have enqueued JQuery and the plug in scripts. Have callled wp_head. Have used no-conflict mode. I am a WordPress beginner but had it working before, hadn’t doen anything to the site for a week or so, revisited it and it had stopped working. It’s just in a testing environment at the moment.

Can anyone suggest what might be going wrong?

<?php wp_enqueue_script("jquery"); ?>
<?php
if ( is_page('home') ) {
   // If it's the home page, we want the slider, otherwise don't bother
   wp_register_script('easyslider',
       get_bloginfo('template_directory') . '/js/easySlider1.7.js');
   // enqueue the script
   wp_enqueue_script('easyslider');
}
?>
<?php
if ( is_page('our-services') ) {
   // If it's the 'our services' page, we want the capty plug-in, otherwise don't bother
   wp_register_script('capty',
       get_bloginfo('template_directory') . '/js/jquery.capty.min.js');
   // enqueue the script
   wp_enqueue_script('capty');
}
?>
<?php wp_head();?>
<?php if ( is_page('home') ) { ?>
<script type="text/javascript">
	jQuery.noConflict();
	jQuery(document).ready(function(){
		jQuery("#slider").easySlider({
			auto: true,
			continuous: true,
			numeric: true
		});
	});
</script>
<?php }; ?>
<?php if ( is_page('our-services') ) { ?>
<script type="text/javascript">
	jQuery.noConflict();
	jQuery(document).ready(function(){
		jQuery('#desktop,#advice,#infrastructure,#web').capty({
		animation: 'slide',
		speed:     400
		});
	});
</script>
<?php }; ?>
