Why doesn't my run script work? Is there something in the code that is missing or misspelled?

game:Service("UserInputService").InputBegan:connect(function(input,gameprocesed)
 if input.KeyCode == Enum.KeyCode.Shift then
  for i = 1,16 do
   wait()
   game.Workspace.Camera.FieldOfView = game.Workspace.Camera.FieldOfView + 1.6
   game.Players.LocalPlayer.Character:WaitForChild("Humanoid").WalkSpeed = game.Players.LocalPlayer.Character:WaitForChild("Humanoid").WalkSpeed + 1
  end
 end
end)

game:GetService("UserInputService").InputEnded:connect(function(input,gameprocesed)
 if input.KeyCode == Enum.KeyCode.LeftShift then
  for i = 1,16 do
   wait(1)
   game.Workspace.Camera.FieldOfView = game.Workspace.Camera.FieldOfView - 1.6
   game.Players.LocalPlayer.Character:WaitForChild("Humanoid").WalkSpeed = game.Players.LocalPlayer.Character:WaitForChild("Humanoid").WalkSpeed - 1
  end
 end
end)

game.Players.LocalPlayer.Character:WaitForChild("Humanoid").Died:connect(function()
 game.Workspace.Camera.FieldOfView = 70
 game.Players.LocalPlayer.Character.Humanoid.WalkSpeed = 16
 script.Disabled = true
end)
