Why is my CameraType not changing in my serverscript?

I made a serverscript that changes the view of the camera. When the script is ran it does not change the cameratype to scriptable and it is not throwing any errors. This script works flawlessly in a localscript but in a localscript the camera will change for all players but with what I'm doing I only want the camera to change for only the player that touched a part.

01	local cam = workspace.Camera
02	local focus = game.Workspace.col1
03	local tween = game:GetService("TweenService")
04	local active = false
05	 
06	game.Workspace.Shop.Touched:Connect(function(hit)
07	    if not active then
08	        active = true
09	        local humanoid = hit.Parent:FindFirstChild("Humanoid")
10	        local player = game.Players:GetPlayerFromCharacter(hit.Parent)
11	        local root = hit.Parent:FindFirstChild("HumanoidRootPart")
12	        Iterator = 1
13	        if humanoid ~= nil then
14	            humanoid.WalkSpeed = 0
15	            cam.CameraType = Enum.CameraType.Scriptable
16	            local ts = TweenInfo.new(0.0001,Enum.EasingStyle.Quad,Enum.EasingDirection.In,0,false,0)
17	            local Goals = {CFrame = focus.CFrame}
18	            local move = tween:Create(cam,ts,Goals)
19	            move:Play()
20	            if root ~= nil then
21	                root.CFrame = game.Workspace.queue.CFrame
22	            end
23	            wait(0.5)

75	 
76	            player.PlayerGui.buttons.Frame.front.MouseButton1Click:Connect(function(player)
77	                if Iterator <= 4 then
78	                    Iterator = Iterator + 1
79	                    local count = tostring(Iterator)
80	                    local val = "col"..count

88	                end
89	            end)
90	        end
91	        wait(2)
92	        active = false
93	    end
94	end)

Also, to fix the camera changing for all players, for the variable "cam" do

local cam = game:GetService("Workspace").CurrentCamera

wich will get only the player's camera.
