Please could someone lend a hand

I have been following this tutorial to make a flash image scroller with only hidden buttons. I really need something like this for a site I am building but I can’t get the script to work. I keep getting an error about this line
[font=Arial]"onLoad(_root.scrollerDirection = “right”;)[/font]
[font=Arial]Can anyone point out the error in this action script ?? [/font]
[font=Arial]I have checked my instance names and X Y positions are all correct, and there doesn’t seem to be any errors in the code attached to the actual scroller.[/font]

That code is indeed wrong, this is what it should be:

_root.scrollerDirection = "right";
