Why my camera system only works in studio and not game?

I am making this Camera tool script for when the player switches to this tool, it hops straight to the camera to focus on the specific part.Unfortunately, this only works in studio due to a LocalPlayer problem. I cant understand how to fix it. any suggestions?

function onSelected(mouse) 
local w = game.Workspace:getChildren()
for i = 1, #w do
if (w[i].className == "Camera") or (w[i].className == "Cam" .. game.Players.LocalPlayer.Character.Name) then
if w[i].CameraSubject == game.Players.LocalPlayer.Character.Humanoid then
w[i].CameraSubject = game.Workspace:findFirstChild("CamCam1")
end
w[i].Name = "Cam" .. game.Players.LocalPlayer.Character.Name
end
end
end 

function onDeselected(mouse)
local w = game.Workspace:getChildren()
for i = 1, #w do
if (w[i].className == "Camera") then
w[i].CameraSubject = game.Players.LocalPlayer.Character.Humanoid
end
end
end

script.Parent.Selected:connect(onSelected)
script.Parent.Deselected:connect(onDeselected)
