CodingForums.com - jQuery object with variable id name. Is is possible?

Hi,
is it possible to passed the jQuery object a variable with the the js functions for example?
I'm having problems with jQuery. I have an img that on click it runs this function however nothing gets hidden or shown.

I have the following in my page header

Code:

function hide_Show(RegionID) 

   var $jQuery = jQuery.noConflict(); 

//Icon that is clicked 

   var objectClickedID = '#' + RegionID + '_img'; 

//Region to hide 

   var objectID = '#' + RegionID; 

   $jQuery(document).ready(function(){ 

      $jQuery(objectClickedID).click(function() { 

        if ($x(objectID).style.display =='none') { 

          $jQuery(objectID).show('slow'); 

        } 

        else{ 

          $jQuery(objectID).hide('slow'); 

        } 

      }); 

}

and my img is as following

Code:

<img id="show_hide_img" onClick ="hide_Show('show_hide'):" alt="Click here to expand/collapse this section" style="cursor: pointer;" src"plus.gif" />

and my region that I want to hide is

Code:

<div id="show_hide">Hide this</div>

I know you might say that I could just hard code the div ID though I have a lot of divs and they img's need to hide specifc divs.

Thanks for your support.
