How To Combine Strength, Endurance, Psychic Leader Stats Into One Leader Stat "Total Power"?

This code looks fine however, you need to refresh the "Total Power" Value each time one of the other stats increase. For example

game.Players.PlayerAdded:Connect(function(plr)
    local leaderstats = Instance.new("Folder", plr)
    leaderstats.Name = "leaderstats"

    local Strength = Instance.new("IntValue", leaderstats)
    Strength.Name = "Strength"

    local Endurance = Instance.new("IntValue", leaderstats)
    Endurance.Name = "Endurance"

    local Psychic = Instance.new("IntValue", leaderstats)
    Psychic.Name = "Psychic"

    local TotalPower = Instance.new("IntValue", leaderstats)
    TotalPower.Name = "Total Power"
    TotalPower.Value = Strength.Value + Endurance.Value + Psychic.Value
    function refresh() --we make a new function so it's easier to refresh later
     TotalPower.Value = Strength.Value + Endurance.Value + Psychic.Value

    end
    for index,value in ipairs(leaderstats:GetChildren()) do --for every stat do

        value.Changed:Connect(function() --whenever the stat changes we want to refresh the total power value
            refresh()
        end)
    end
end)

(This code may not work, I haven't tested it.)
