Hi friends,

Is there a way to convert this vertical scrolling into horizontal scrolling from this javascripts below?

Much appreciated!!

HTML Code:

// 3/25/2001
// added scrolling in any direction and initTop, initLeft

//
// 3/30/2001
// fixed bug that occured when if you called scrollTo( )
// and the new position was the same as the current
// position. that was stupid.
//
// 4/02/2001
// small bug fix - on some browsers, on slow connections
// the script would not run at all. to be sure the doc
// is done loading before .load() is called, the author
// must now call the .load() method in the onload handler
// for the page.
//
// 8/22/2001
// if you tried to scroll before page was loaded it threw
// an error. this should be fixed now.
