how do i disable these two GUIs?

basically this code is meant to disable some GUI, it works, but Inventory And DInventory Do Not Get Disabled.

        for i,v in pairs (game.Players:GetChildren()) do
            v.Team = game.Teams.Survivors
            local machinegui = v.PlayerGui:WaitForChild('Machines')
            machinegui.Enabled = true
            local ib = v.PlayerGui:WaitForChild('InventoryButton')
            ib.Enabled = false
            local dib = v.PlayerGui:WaitForChild('DInventoryButton')
            dib.Enabled = false
            local i = v.PlayerGui:WaitForChild('Inventory')
            i.Enabled = false
            local di = v.PlayerGui:WaitForChild('DInventory')
            di.Enabled = false
            local s = v.PlayerGui:WaitForChild('RobuxShop')
            s.Enabled = false
        end
