Why is my local script not running locally ?

Hello! I created a local script for checkpoints, but for some reason it does not work locally. What could be the problem?

local player= game:WaitForChild("Players").LocalPlayer
local character = player.Character
local CheckpointData = script.CheckpointData
local CheckpointValue =  script.CheckpointData.CheckpointValue


for i, v in pairs(game.Workspace.CheckpointFolder:GetChildren()) do
    if v:IsA("Part") then

  function onTouch()
    CheckpointValue.Value=v.Position
end

    v.Touched:connect(onTouch)
    end
end

for i, v in pairs(game.Workspace.Obby.KillPart:GetChildren()) do
    if v.Name == "KillPart" then
        function onTouch()
                player.Character:MoveTo(CheckpointValue.Value)
                game.ReplicatedStorage.Death:FireServer(player)
            end
        end
    end

    v.Touched:connect(onTouch)
end
