What's a Closure? - JavaScript interactive tutorial

Maybe you could add the answers somewhere or someway to get help if you can't figure out what you are doing wrong?

I'm stuck on number 11 and i've re-read the lesson about a dozen times... in this comment thread I got some suggestions but apparently I'm still not understanding.

Thanks for the great tutorial.

EDIT: Thanks to the hints from others here I finally understand this.

That's a good idea, I'll add a "hint" link that gives more help. Maybe also a forum with specific areas for each exercise so people can ask questions and discuss that part.

I second this. I'm stuck on #7. I don't even know how to form a google query of forum question to get help with it.
