Need help with behavior sprite

I'm new to RPGMaker VX Ace and I'm trying to use one of the behavior sprite and I can't get it to work. :|

When I put a behavior sprite in ( the jump roping kid.) It dosen't move.

Never mind I found out how to do it. :p

If you need help, the first thing you should do is be as detailed as possible with your question :) We can't help if you don't specify which behaviour sprite.

Incidentally, I did write a blog post mentioning behaviour sprites.

You need to state what you're doing with it and what doesn't work, because we have no crystal balls showing your computer screen.
At a guess (the most common problem) the behaviour sprite is changing when the player tries to access it - if that happens, you forgot to check the "direction fix" option bottom left.
