I Need A Little With This Browser Scroll Position Script!

[designer76]

Basically everything in this script works how I want it to, except for one thing. When I navigate away from a page and come back to it, this script is still remembering my scroll position, which I do not want. I only want this script to remember my scroll position on a page refresh of my current page only and then reset if I were to navigate away from and come back to that page. How would I go about modifying this script to work how I want it to?

 

Thanks in advance for any help given.
