How do i fix 19:52:21.443 - Touched is not a valid member of Script?

My Script

script.Parent.Touched:Connect(function(hit)
    local char = hit.Parent
    local hum = char:FindFirstChild("Humanoid")
    if hum and char.Name ~= script.Parent.Parent.Name then
        hum.Health = hum.Health - script.Dmg.Value
        script.Disabled = true
        wait(.5)
        script.Disabled = false
    end
end)

The error

19:52:19.815 - LocalizationService.RobloxLocaleId overridden to "en-us" (x2)
19:52:21.443 - Touched is not a valid member of Script      ---- this the error
