                     nRelativeScrolling : in number optional ): boolean;

Parameter	Description
nTop	The vertical position of the scrollbar. If nRelativeScrolling is set to `BROWSER_RELATIVE_SCROLLING` this is the offset that is added. Set this parameter to `BROWSER_NO_SCROLL` if you only want to scroll horizontally.
nLeft	The horizontal position of the scrollbar. If nRelativeScrolling is set to `BROWSER_RELATIVE_SCROLLING` this is the offset that is added. Set this parameter to `BROWSER_NO_SCROLL` if you only want to scroll vertically.
nRelativeScrolling	Optional: If this value is set to `BROWSER_RELATIVE_SCROLLING`, the values of nTop and nLeft are interpreted as offsets.
