How do I get rid of this error for my License Plate System?

I'm trying to make a License Plate that generates a player username ID when they enter into a vehicle. I made a car already but just need this generator system to be connected to it. I believe the block of code is wrong because I see an error under local.

Please READ carefully..thank you!

LicensePlateGenerator

local function SurfaceGui()

script.Parent.Handle.SurfaceGui["Id:"].Identification.Text = game.Players.LocalPlayer.UserId

for i = 1, #pattern do
    local c = string.sub(pattern, i, i)
    if (c == "0") then
        plate = plate..tostring(math.random(0,9))
    elseif (c == "X") then
        plate = plate..string.char(math.random(65,90))
    else
        plate = plate..c
    end
end

for i,v in pairs(script.Parent.Plates:GetChildren()) do
    v.SGUI.Identifier.Text = plate
end

script.Parent.Touched:Connect(function(hit))
    local h = hit.Parent:FindFirstChild("Humanoid")
    if h then
    script.Parent.Touched:Connect(function(hit)
    local h = hit.Parent:FindFirstChild("Humanoid")
    if h then
        script.Parent.Handle.SurfaceGui["Id:"].Identification.Text = game.Players[hit.Parent.Name]

        for i = 1, #pattern do
                local c = string.sub(pattern, i, i)
             if (c == "0") then
                 plate = plate..tostring(math.random(0,9))
         elseif (c == "X") then
                plate = plate..string.char(math.random(65,90))
         else
              plate = plate..c
      end
end

    for i,v in pairs(script.Parent.Plates:GetChildren()) do
         v.SGUI.Identifier.Text = plate
    end
end
end
