Camera Manipulation help pls?

So, this is my first time trying out manipulation, so I have legitimently NO idea on how it works, I tried this, thinking it was right, but it's not. What am I doing wrong?

local c = game.Workspace.CurrentCamera

game.Workspace.Main.ChangeCamera.Changed:connect(function()
    if game.Workspace.Main.ChangeCamera.Value == true then
            c.CoordinateFrame = CFrame.new(game.Players.LocalPlayer.Character.Head.Position) --here
            c.CameraType = "Custom"
            else
            c.CameraSubject = game.Workspace.CameraSubjecter
            c.CameraType = "Scriptable"
        end
end)
