Help with filtering content!

Help with filtering content!

I am attempting to filter content using multiple class names, but I can't seem to be able to get the content to be filtered based on their class names. Here's the code I have so far:

  1.       $(document).ready(function(){
      $('#sorter a').click(function(e){
        var sortName = $(this).text().toLowerCase().replace(' ','-');
        if(sortName === 'all-images') {
           $('#photorow1 li').show().removeClass('hidden');
        } else {
           $('#photorow1 li').filter(sortName).show().removeClass('hidden')
                       .end().not(sortName).hide().addClass('hidden');
        }
        e.preventDefault();
      });
    });     










Any help would be greatly appreciated!!
