Superfish problem

Superfish problem

Hi. I am new to jQuery and (JavaScript in general), and I decided to use Superfish on my latest web project. Basically, this site stores the HTML contents to be displayed on each page in a database, and I have a PHP script that takes the name of the page to be displayed and fetches the contents of that page from the database. Simple, right? Well, I have been tinkering with the code, and I can't quite get it right.

Here is the jQuery code I am using:
  1. <script type="text/javascript"> 
  2.  
  3.     $(document).ready(function(){
  4. var scrollbar = $("#scrollbar1");
  5. scrollbar.tinyscrollbar();
  6. $("a.menu").click(function(){
  7. $.get("populate.php", {name: $(this).html()}, function(data){
  8.                                 if (data != "blank") {
  9.               $("#dyn").html(data);
  10.       scrollbar.update();
  11.                                 }
  12. },
  13. "html");
  14. });
  15.         $("ul.sf-menu").supersubs({ //For some reason, this is interfering with the content-grabbing code
  16.             minWidth:    12,   // minimum width of sub-menus in em units 
  17.             maxWidth:    27,   // maximum width of sub-menus in em units 
  18.             extraWidth:  1     // extra width can ensure lines don't sometimes turn over 
  19.                                // due to slight rounding differences and font-family 
  20.         }).superfish();  // call supersubs first, then superfish, so that subs are 
  21.                          // not display:none when measuring. Call before initialising 
  22.                          // containing tabs for same reason.
  23.     }); 
  24.  
  25. </script>
When I click on a top-level menu link (other than the very first menu link on the page), it simply clears the div with the id "dyn." When I comment out the code that calls Superfish, everything works great. I know that there is some sort of conflict between that superfish does when I click on a menu link and what my code is trying to do, but I do not know enough about jQuery to figure out what is going on. I would really appreciate some help!

Thanks so much in advance!
