A little help for a platform game?

[MYMOM105]

So I'm trying to make a platform game, and I'm adding the crouch part. I'm wanting to make it so that whenever the character crouches, he can't move (this will be for dodging bullets and whatever). The only problem is that whenever I crouch down, the animation stays at crouch when I stop pressing the crouch button. I have tried doing "Always-Make character stand up straight" and hope that the crouch command would overpower it. Is there a command that basically says "Always Unless Another Button is Being Pressed"?

Hey there. I'm not very good at explaining things so I made a real quick example of how to do a crouch scenario, then resume standing when crouch button is released. I know it's a real crude setup. It's basically just a square active object that changes color based on it's status. Yellow means it's standing up, and as long as you hold the down button it will turn red to indicate it is crouching. When you release the button which is the down arrow key, it will resume standing. There's no physics or anything here, just a basic animation sequence change, but should give you the basic concept you're looking for I hope. Hope this is what you were trying to achieve.
