I thought this code was universal but apparently it is not. I am trying to get the scroll height of a frame and Firefox and Chrome return a value of 0 instead of 880 that IE is returning.

      loIFrame=document.getElementById('IFrameMenu')
      loIFrameDocument=loIFrame.contentDocument || (loIFrame.contentWindow && loIFrame.contentWindow.document)
      alert(loIFrameDocument.body.scrollHeight)

Anyone would know what would need to be adjusted?
