why isnt it getting the player scripts attribute? (if it even should be called attribute)

--[ Variables ]--
local character = script.Parent
local plr = game.Players:GetPlayerFromCharacter(character)
local guns = plr:WaitForChild("PlayerScripts")
local random = 0

--[ Main Code ]--
if random == 0 then
    random = math.random(1,2)
    if random == 1 then
        guns.Revolver.Disabled = false
    end
    if random == 2 then
        guns.Ak47.Disabled = false
    end
end

Script says that it has an infinite yield on it, confused on what that means, can somebody help me? This is a regular script inside of the StarterCharacterScripts folder inside of the StarterPlayer folder. There are 2 scripts inside of the StarterPlayerScripts called Revolver and Ak47 that make the guns appear on the screen.

Sincerely,
