scroll bar is missing while resizing

Hi,
I am resizing my frame height according to the window content length but some time the scroll bar is missing, this is happening randomly, any help is greatly appreciated.
Thanks in advance

re: scroll bar is missing while resizing

if your frame is set with the scroll bars as automatic, then it would disappear if the ocntent of the page does not exceed the size of the frame. If you want this to always show, change the scroll bar setting to true.

hi,
Thanks for your reply. I think I asked question wrong. I am resizing my I frame height using below javascript, calling it on the onLoad of iframe.
function calculateHeight()
{
document.getElementById('waitResults').height = 100;
//find the height of the internal page
var the_height=
document.getElementById('waitResults').contentWind ow.document.body.scrollHeight;

//change the height of the iframe
document.getElementById('waitResults').height=the_ height;
}

But some time the value of the_height is less than the real value and because of the I some of the data on page is not able to seen by user. Some time I am getting the correct value and that time my page looks fine.

I greatly appreciate your help.

Then this is a javascript question and I'll transfer you there.
