How to scroll SharePoint Web Parts page down from Java Script?

Hi All,

I have to implement a scroll down button in my Web Part. I tried the script below in my button and MOVEBOTTOM anchor at the bottom of the page but this approach does not work. It has moved the page down till GoToBottom button hited top static SharePoint area and doeas not really scroll to the bottom of the page. 

OnClientClick="document.getElementById('MOVEBOTTOM').focus();window.location.hash = '#MOVEBOTTOM'; return false;"
