PlayerGui children not working? [UNANSWERED]

script.Parent.Touched:connect(function(hit)
    local player = game.Players:GetPlayerFromCharacter(hit.Parent)
    if player then
        local playergui = player:WaitForChild("PlayerGui")
        if playergui then
            local shophud = playergui:WaitForChild("ShopHUD")
            if shophud then
                local shopframe = shophud:WaitForChild("ShopFrame")
                if shopframe then
                    shopframe.Visible = true
                end
            end
        end
    end
end)

This seems to stop at line 6 when I add prints to see where it will stop. Their is no error in the output, and it works on Play Solo, but not on servers or online. Please help.
