A localscript in a tool doesnt know a local i made in serverscriptservice?

hi everyone, so i made this click-detector, but it wont add points. This script is in a normal script in serverscriptservice:

game.Players.PlayerAdded:Connect(function(player)
    print("LeaderStats")
    local stats = Instance.new('IntValue', player)
    stats.Name = 'stats'

    print("Stats")
    local IQ = Instance.new("IntValue", stats)
    IQ.Name = "IQ"
    IQ.Value = 0
end)

This is a script inside of a tool in the starterpack:

script.Parent.Parent.Equipped:Connect(function(mouse)
    mouse.Button1Down:Connect(function()
        print ("clicked")
        IQ.Value = IQ.Value + 1
    end)
end)

In the output it says that IQ is not defined... how do i allow the localscript to use a local from the serverscriptservice?
