What the freak is making the wood step looperoni??

It loops the wood sound WAYYY too much when it's not even on wood. Please help me fix this script as I'm counting on it for a shooter I'm making

wait(1)
for i,v in pairs(game.Players.LocalPlayer.Character.Head:GetChildren()) do
    if v:IsA("Sound") then v:Destroy() end
end
function StopAllSounds(c)
    for i,v in pairs(script:GetChildren()) do
        if v:IsA("Sound") then
            if v.Name ~= c then v:Pause() end
end
    end
end

playstone = false
playmetal = false
repeat
    if game.Players.LocalPlayer.Character.Humanoid.moveDirection ~= Vector3.new(0,0,0) and game.Players.LocalPlayer.Character.Humanoid.Jump ~= true then
        print(game.Players.LocalPlayer.Character.Humanoid.FloorMaterial)
        if game.Players.LocalPlayer.Character.Humanoid.FloorMaterial == Enum.Material.Wood or Enum.Material.WoodPlanks then
            StopAllSounds() playwood = false playstone = false playmetal = false
            if playwood == false then
                playwood = true
                print('Playing Wood')
