Iframe Auto Re-Size

[kaos]

Any way... I'm just trying to improve the code i showed you on my first post:

<!--
function calcHeight()
{
  //find the height of the internal page
  var the_height=
    document.getElementById('content').contentWindow.
      document.body.scrollHeight;

  //change the height of the iframe
  document.getElementById('content').height=
      the_height;
}
//-->

The problem is its getting bigger, but not smaller (except in IE).
