How to activate other fireball with disabling the first fireball?

I'm trying to make a script where whenever you press a key, it launches a fireball. To be honest, the script and localscripts work, but I'm trying to make something in the script where whenever the boolvalue is true, it activates the other fireball. For example, if the green fireball boolvalue is true, and the other fireballs' boolvalue are false, the green fireball launches. I'm trying to make that, but it won't work. It only works when the green fireball's boolvalue is automatically true, and that it won't work when I maunally turn on the boovalue to true, and disable the other fireballs' boolvalue. Also there are no errors. Help? (also, even if you disable the fireball value, it still fires? and tried repeat wait() until, still no work.)

I only have two fireballs so far, you can see both scripts:
