 * Guys i’m desperately need a LOT of help right now.
 * I’ve tried every single combination for my jQuery to interact with my website,
   but prototype is already interacting, so its already used the $ variable.
 * I’ve already did
 *     ```
       <?php wp_enqueue_script('jquery'); ?>
       <script type="text/javascript">
       jQuery(document).ready(function() {
       jQuery('#tabslide > ul').tabs({ fx: { height: 'toggle', opacity: 'toggle' } });
       });
       </script>
       ```
   
 * but I get this error:
    **jQuery(“#tabslide > ul”).tabs is not a function**
 * I’ve also tried this:
 *     ```
       <script type="text/javascript">
       jQuery(function($) {
       $(document).ready(function() {
       $('#tabslide > ul').tabs({ fx: { height: 'toggle', opacity: 'toggle' } });
       });
       });
       ```
   
 * </script>
 * but I get this error:
 *     ```
       Firebug's log limit has been reached. %S entries not shown.		Preferences
       [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMViewCSS.getComputedStyle]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://websitename.com/wp-includes/js/jquery/jquery.js :: anonymous :: line 11" data: no]
       ```
   
 * I’ve also tried this:
 *     ```
       <?php wp_enqueue_script('jquery'); ?>
       <script type="text/javascript">
                   jQuery.noConflict();
                   jQuery(document).ready(function() {
                   jQuery('#tabslide > ul').tabs({ fx: { height: 'toggle', opacity: 'toggle' } });
                   });
       </script>
       ```
   
 * but it still spat back out at me and did this:
 * `jQuery("#tabslide > ul").tabs is not a function`
    and another error message
 *     ```
       $ is not a function
       <em>[Break on this error]  var query = document.evaluate(expression, $(parentElement) || document,</em>
       ```
   
 * which was located at prototype.js on line 1263.
 * I need all the help I can get! Please help me.
 * I’ve tried using this code as well
    `jQuery(function($) { /* insert jQuery code
   here */ });`
 * but it just outputs a more error messages. help!

 * YES! resolved.
 * GUYS! MAKE SURE YOUR SCRIPTACULOUS.JS script file is BEFORE your jQuery.JS FILE!
 * ie:
 *     ```
       <script src="scriptaculous.js" type="text/javascript"></script>
        <script src="jquery.js" type="text/javascript"></script>
       ```
   
 * and it should work.
 * i used the code
 *     ```
       <script type="text/javascript">
               jQuery.noConflict();
   
               jQuery(function($) {
                   $(document).ready(function() {
                       $('#tabslide > ul').tabs({ fx: { height: 'toggle', opacity: 'toggle' } });
                   });
               });
           </script>
       ```

 * I am trying to utilize jquery to create this effect in my navigation:
 * [http://devthought.com/cssjavascript-true-power-fancy-menu/](http://devthought.com/cssjavascript-true-power-fancy-menu/)
 * Problem is it wont work in WP for me.
 * I tried moving the jquery scripts below scriptaculous but it breaks my glider
   and lightbox script.
 * Any help would be great!
