How to prevent player movement?

while true do
    wait(0.1)
    if game.Players.LocalPlayer.leaderstats.Stop.Value == 1 then
        RunService:BindToRenderStep('Control', Enum.RenderPriority.Input.Value, 
                onUpdate)
        ContextActionService:BindAction('Left', onLeft, true, 'a', Enum.KeyCode.Left,               
                Enum.KeyCode.DPadLeft)
        ContextActionService:BindAction('Right', onRight, true, 'd', Enum.KeyCode.Right,        
                Enum.KeyCode.DPadRight)
        ContextActionService:BindAction('Jump', onJump, true, 'w', Enum.KeyCode.Space, 
        Enum.KeyCode.Up, Enum.KeyCode.DPadUp, Enum.KeyCode.ButtonA)
        end
    if game.Players.LocalPlayer.leaderstats.Stop.Value == 0 then
        print("SSSSSS")
        RunService:BindToRenderStep('Control', Enum.RenderPriority.Input.Value, 
                onUpdate)
        ContextActionService:BindAction('Left', onLeft, false, 'a', Enum.KeyCode.Left,  
        Enum.KeyCode.DPadLeft)
        ContextActionService:BindAction('Right', onRight, false, 'd', Enum.KeyCode.Right, 
        Enum.KeyCode.DPadRight)
        ContextActionService:BindAction('Jump', onJump, false, 'w', Enum.KeyCode.Space, 
        Enum.KeyCode.Up, Enum.KeyCode.DPadUp, Enum.KeyCode.ButtonA)
    end
end

So, this script it's supposed to not allow player movement if a leaderstat called "stop" == 0. It's a snippet of a larger script, but this is all that really matters.

Yes, it does register whenever the value is changed i checked.

Can someone tell me what i did wrong here?

PS ( Yes hiimgoodpack, I indented specifically so you wouldn't put me on your kill list.)
