How do you make a camera follow a person but still be able to move the camera?

I was able to get the camera to follow a person, but the camera position doesn't move. Just the angle. I am using a hopperbin tool. And this is a localscript which is a direct child of the hopperbin.

Cam = game.Workspace.CurrentCamera
Player = script.Parent.Parent.Parent
Count = 0

function onKeyDown(key) 
    Players = game.Players:getChildren()
    lkey = key:lower()

    if lkey == "e" then
        Count = Count+1
        if Count>#Players then
            Count = 1
        end
        if Players[Count]~=Player then
            Cam.CameraSubject = Players[Count].Character.Head
        else
            Count = Count+1
            if Count>#Players then
                Count = 1
            end
            Cam.CameraSubject = Players[Count].Character.Head
        end
    end
    if lkey == "q" then
        Count = Count-1
        if Count<1 then
            Count = #Players
        end
        if Players[Count]~=Player then
            Cam.CameraSubject = Players[Count].Character.Head
        else
            Count = Count-1
            if Count<1 then
                Count = #Players
            end
            Cam.CameraSubject = Players[Count].Character.Head
        end
    end
end
function UnEquipped()
    game.Workspace.CurrentCamera.CameraSubject = game.Players.LocalPlayer.Character.Humanoid
    game.Workspace.CurrentCamera.CameraType = "Custom"
end
function onSelected(mouse) 
mouse.KeyDown:connect(onKeyDown) 
end 
script.Parent.Deselected:connect(UnEquipped)
script.Parent.Selected:connect(onSelected)
