Placing Multiple Editors on One Page - Is this possible?

Is it possible to have 2 editor boxes on a single page? Whenever I try to do this, the first one always comes up as a textbox and the 2nd is the FCK editor box.

Here is my code, any help would be appreciated:

<script type="text/javascript">
window.onload = function() {
   var oFCKeditor = new FCKeditor('prod_ldesc');
   oFCKeditor.BasePath = "../fckeditor/";
   oFCKeditor.Height = "250";
   oFCKeditor.ToolbarSet = "auto";
   oFCKeditor.ReplaceTextarea();
  }
</script>
<textarea id="prod_ldesc" name="prod_ldesc"></textarea>

<!-- further down the page -->

<script type="text/javascript">
window.onload = function() {
   var oFCKeditor2 = new FCKeditor('prod_notes');
   oFCKeditor2.BasePath = "../fckeditor/";
   oFCKeditor2.Height = "250";
   oFCKeditor2.ToolbarSet = "auto";
   oFCKeditor2.ReplaceTextarea();
  }
</script>
<textarea id="prod_notes" name="prod_notes"></textarea>
