How to give a "weapon" when spawned?

When the character spawns in the game I tried to give them a weapon. Here is the script that some reason DIDN'T error, but it won't work properly.

function Security(plr)

if plr:IsInGroup(1056046) and plr:GetRankInGroup(1056046) == 38 or 255 then

    local Sw = game.ServerStorage.LinkedSword:Clone()

local HoldIT = plr:WaitForChild(game.Players.localPlayer.Backpack)

    wait(HoldIT)

Sw.Parent = plr.Backpack

    print("Sword Was Given")
else
    print("Sword Wasn't Given")
end

end

    game.Players.PlayerAdded:connect(Security)

Sorry if you can't read it.

How do I get it so whenever they spawn into the game they'll get a weapon called LinkedSword

Comment for questions! Thanks for the help!!
