What's the way to make it where crouching would cancel the sprint?

I've been messing around with this gun script. I have a way to make the sprint cancel the crouch and I can't do it the other way around. How would I do it?

Also another thing is, when I do cancel the crouch with the sprint, how would I make the wait time 0 so the player can crouch once he presses C? Doing Wait (0) doesn't work.

function bindings.KeyPressed(key, mouse)
	local key = key:lower()
	if key == "r" and not reloading and not mouseDown then
		gun.Reload(mouse)
	elseif key == "f" and not reloading and not mouseDown then
		if armToggle.Value then
			armToggle.Value = false
			char.Humanoid.WalkSpeed = 16
			defaultanimation:Play()
			sprintanimation:Stop()
		else
			armToggle.Value = true
			char.Humanoid.WalkSpeed = settings.sprintspeed
			crouchanimation:Stop()
			sprintanimation:Play()
		end
	elseif key == "c" and not armToggle.Value then
		if crouch then
			crouch = false
			char.Humanoid.WalkSpeed = 16
			defaultanimation:Play()
			crouchanimation:Stop()
		else
			crouch = true
			char.Humanoid.WalkSpeed = settings.crouchspeed
			sprintanimation:Stop()
			crouchanimation:Play()
		end
	end
end
