[as3] For loop + getchildbyname

Hello everyone, I have a little problem in my game. I have made 30 movieclips for my level selection screen. Then I create a movieclip with the same name using a for loop. With that code I make roll_over function showing a Tooltip.
I then want to trace what button is being clicked. My whole code is here:

I want to trace what button is clicked, so I can show it on my tooltip textbox.

Can anyone please help me with this.

Regards,
Mvrb

EDIT it is fixed now
