I maintain the website for www.walnutcreekrec.org

We have a proprietary registration system which you can see at:
http://ezreg.walnutcreekrec.org/Acti...sp?SectionId=1

We have setup an iframe (without your script) which you can see at:
http://www.walnutcreekrec.org/ezreg.html

That iframe has a set height of like 3000 pixels because the "HELP DESK" section has such a large height. I do not want all that white space.

As you will notice by clicking around the proprietary registration in the iframe, the user menu does some drastic changes in height. I would like the frame to acclamate to these changes.

You can see where I have attempted your script at:
http://www.walnutcreekrec.org/ezregtest.html

For some reason it does not even detect the height properly the first time, and in Firefox it has a scroll bar, but in IE it does not and is just cut off. Is there something I am doing wrong? Is this too complicated for an iframe? If so, what do you recommend?

Thanks.
