I'm using this function to keep a div on the screen when the page is scrolled down. This work fine, however it seem to break some other jQuery code (in the wordpress). The problem is with the following function. If i remove it, other code works fine. Can someone suggest what can be problem with following code:

```
jQuery(document).ready(function($){ 
    jQuery.event.add(window, "scroll", showbar);
    var sharebar = jQuery('#showbar');
    var start = jQuery(sharebar).offset().top;
        function showbar() {
            var p = jQuery(window).scrollTop();
            jQuery(sharebar).css('position',((p+10)>start) ? 'fixed' : 'absolute');
            jQuery(sharebar).css('top',((p+10)>start) ? '10px' : '');
        }   
});

```

Edit: What I meant by 'breaking the code' was that, if i include a javascript having this code in my wordpress theme. The javascript of the wordpress will not work in the control panel of the theme (eg. no lightbox popup by clicking the image upload button etc). The wordpress controls will start working as soon as i remove this code. So obviously theres something wrong with this code.

**Edit 2:**

I dont seem to get any js errors but i noticed if i wrap the code in `(function() { .. })();` instead of `jQuery(document).ready(function($){` then the wordpress does not have any problem, but then my code does not work. Can you suggest how can i use function() instead of jQuery(document).ready.. Sorry but i dont have much knowledge of jquery.
