title: If variable = number, do X, else do nothing
body: <p>I wrote a jquery code that is going to expand certain elements on hover. I want the code to only expand if not expanded. Here is my code. It doesn't seem to be working correctly.</p>
  
  <pre><code>$(document).ready(function() {
      var labelstatus = 0;
  });
  $(document).ready(function() {
      $("a.rm").hover(function () {
          if (labelstatus != 1){
              $("#expensereduction,#envimpact,#mtextlft,#initaud,#energaud").fadeOut();
              var currentFontSize = $('.initiate').css('font-size');
              var currentFontSizeNum = parseFloat(currentFontSize, 10);
              var newFontSize = currentFontSizeNum*3;
              $('.initiate').delay(500).animate({
                  fontSize: newFontSize
              });
              return false;
              var labelstatus = 1;
          }
          else {
          }
      });
  });
  </code></pre>
