jquery marquee with previous next buttons?

I'm using jQuery marquee and I'm trying to see how to add previous / next buttons, I've tried messing with the function "showNext" but not having any luck. The code I'm using is found here:

Mention of adding prev/next buttons is here:

But I can't seem to add the buttons and get it working. If someone could help me, that would be fantastic!!

Cheers :)

Perhaps this one would suit your needs better. Looks like it already has next and previous built in.
