How to fix a Live Currency BackPack Script?

-- Energy

}

local text1 = tostring(math.floor(abbreviatedNumber))

for abbreviation, digits in pairs(abbreviations) do
    if #text1 >= digits and #text1 < (digits + 3) then
        chosenAbbreviation = abbreviation
        break
    end
end

    local rounded = math.floor(abbreviatedNumber / 10 ^ (digits - 2)) * 10 ^ (digits - 2)
    text1 = string.format("%.1f", rounded / 10 ^ (digits - 1)) .. chosenAbbreviation
else
    text1 = abbreviatedNumber

end

local Strength = Player.leaderstats.Strength
    script.Parent.Text = text2.."/"..text1
Strength.Changed:Connect(function()
    script.Parent.Text = text2.."/"..text1
end)

ummm... if you're using a local script, make sure to just define player like

local Player = game.Players.LocalPlayer

and to make it a "live" count, just use Loop to keep checking the player's stat and make the number that.
