Illustrator starburst effect help

Hey guys. I’m trying to teach myself some Illustrator, so I’m trying to make this starburst. I’m trying to follow this tutorial:

I can’t even get past the first step though! Here’s my problem: I can’t figure out how to change the star’s number of points. Within Illlustrator, I can’t find any sort of option bar (like in PS) or even a palet. Can someone tell me where I can find that?
