I'm trying to make a quiz on Powerpoint.

So I have a RED box and a BLUE box, and they are both set to animations that go down.

I want to be able to press the Red box and that moves down, and then press the Blue box so that moves down, but I need it to work so that sometimes when people choose blue that will go down, and then they might choose it again so I need it to go down again, but I can't do it with the 'order' as they just do it in a certain order that you choose first.
