Menu buttons - OOP

hi,
I was learning how to go with this OOP thing and tring the introductionToOOP tutorial found in gotoandlearn.com.
understood it really well but the thing is I can’t find a way to make this work if i want th buttons to change color or go to a different frame after the release.

example:
if i press bot n.01 it will turn orange (like selected), after that i press n.03 it will turn orange…but first it will turn the bot n.01 to first state!

I’ve done this already by the hard way, like making visible = true…and having a orange copy of the bot behide the bot… but i would like to know if someone can help me out doing this the OOP way :pope:

thx
