Its now working.
Because at the bottom of the page one link is available.
When i click the link, it goes to another page.
when i click the browser back button, it should go to the top of the page. but, its not happen here.
Can you give any suggession.
I added one code for that in onload,
its working fine with netscape and internet explorer for Windows.
In MACOS internetexplorer its not working.
