How can I show the answer of different buttons with if else?

Hi~
I want to build up a botton that can show out the answer of another button.

I thing I can do like this ... but I don't know hoe to write the code in adobe animation

EX:

buttonA be clicked and buttonZ is also be clicked

then

show pictureA

buttonB be clicked and buttonZ is also be clicked

then

show pictureB

buttonC be clicked and buttonZ is also be clicked

then

show pictureC

when only press button A ,B,or C,  without press button Z   --->      shows nothing
