title: jquery parameter offsetY not working
body: <p>Im using a jquery plugin stickyfloat to create a floating sidebar on my webpage. </p>
  
  <p>demo: <a href="http://jsfiddle.net/neo3000ultra/vkvvX/" rel="nofollow">http://jsfiddle.net/neo3000ultra/vkvvX/</a></p>
  
  <p>By default, the sidebar appears at the top right corner of its parent container, I want the sidebar to stay at the right bottom corner of the container, so I gave it an <code>offsetY</code> parameter according to its documentation.</p>
  
  <pre><code>$('#menu').stickyfloat({offsetY: 500});
  </code></pre>
  
  <p>But not matter how I change the value of the <code>offsetY</code>parameter, the position of the sidebar does not change. It seems that that parameter is not working.</p>
  
  <p>So can anyone please help me with this? Thanks in advance!</p>
