Why won't this Invisible tool work in servers?

##Problem

The script appears to be loading before the character and its elements began to load.

##Solution

I added a wait function to a CharacterAdded event to return the character once the Character was added. The script appears to be loaded and executed before the character can be added. Also, FindFirstChild was returning Torso as nil, so line 3 in the script below can act as a if then statement somewhat. It's basically going if FindFirstChild returns nil, then wait for the WaitForChild to find something.

##Final Script

local Player = game.Players.LocalPlayer
local Char = Player.CharacterAdded:wait()
local Torso = Char:FindFirstChild'Torso' or Char:WaitForChild'Torso'

enabled = true

game:GetService("UserInputService").InputBegan:connect(function(input,proc)
    if input.KeyCode == Enum.KeyCode.E then
        if enabled then
            enabled = false
            Torso.Transparency = 1
            wait(5)
            Torso.Transparency = 0
            enabled = true
        end
    end
end)
