How to make brick give more than one point?

function onTouched(hit)
    local player = game.Players:GetPlayerFromCharacter(hit.Parent)
    if player then
        local gui = player.PlayerGui.PointsGui.PointsFrame.Points
        local points = tonumber(gui.Text)
        if points == nil then points = 0
            points = points + 1
            gui.Text = points
        end
    end
end

script.Parent.Touched:connect(onTouched)

The text will change to 1, like it says in the script, but it wont go any higher, can anyone help me with this? Thanks a million! :)
