Hello everyone:

I am working on a page that contains a table which runs off of the screen (vertically) in low screen resolutions, but not in high resolutions.  Up until now I have been making the scroll bar appear in low resolutions but not in high ones using the following CSS:

 html,body
  { margin:0;
     padding:0;
     height:100%;

     <?php if ($ScreenHeight > 768)
       { ?> overflow:hidden; <?php } ?>

     border:none;
   }

But this is not enough any longer.  Different users have different amounts of available vertical space, and this code may turn off the scroll bar when it shouldn't or not turn it off when it should.  I am able to calculate the pixel height of all of the tables on the page using offsetHeight, and I need to set the overflow property based on the numbers I get from offsetHeight.  The problem is that when I try to access the overflow property using document.body.style.overflow, which is a command format that I have seen in several tutorials, when I try to print out its value I always get nothing, and when I try to set its value to "hidden" it has no effect on the page.

What command do I need to set the overflow property using Javascript?

Thanks for your help,
Tom Richey
