Collision Detection for Character Crouching Not Working in Unity 3D - unity3d

Question

I was following a tutorial but I'm having trouble with the CheckCollisionOverlap() function. It's meant to check for a collision over the player's head when the player is crouching, but for some reason he won't stand back up (or stop walking in place).
If I comment out PhysicsUpdate() and CheckCollisionOverlap(), he will crouch, walk crouch, and stand up from crouch, so I know the problem has to exist within that logic.
In the tutorial comments section, someone mentioned that they changed the value of the layermask. I named a layermask Player and assigned it to layer 8 but that still didn't do anything.

I had to change all the layers of the children in the player gameobject as well. Not really sure why that worked, but its responding.
