Why is this camera view changing script only working in ROBLOX studio?

I have a server script to give the below localscript to the player:

game.Players.PlayerAdded:connect(function(player)
    player.CharacterAdded:connect(function(character)
        script.CameraClient:clone().Parent = character
    end)
end)

This is the localscript only working in studio:

local cam = workspace.CurrentCamera
cam.CameraSubject=workspace.woofwof
cam.CameraType = "Attach"
cam.CoordinateFrame=CFrame.new(10,10,10)
cam.Focus=CFrame.new(20,3,2)
