Why doesn't this PlayerAdded script work?

I made a script that gives me or the solo test "Player" a tool when they join a game. However, it doesn't work, and the output doesn't tell me anything. Here is the script.

local Players = game:GetService("Players")

function onPlayerAdded(player)
    local l = game.ServerStorage.LASM:Clone()
    if player.Name == "Wizardel" or player.Name == "Player" then
        l.Parent = player.Backpack
    end
end

Players.PlayerAdded:connect(onPlayerAdded)

for _,player in pairs(Players:GetPlayers()) do
     onPlayerAdded(player)
end

I need the

for _,player in pairs(Players:GetPlayers()) do
     onPlayerAdded(player)
end

bit so that it works in Solo Test mode. Can anybody help?
