I need help with some gui-stat changing commands?

admins = {"HydroDivinity"}

game.Players.PlayerAdded:connect(function(pl)
    for i,v in pairs(admins) do
        if v == pl.Name then
            pl.Chatted:connect(function(mes)
                if mes:sub(1,8):lower() == ":change " then
                    local name, textvalue = mes:match("(%w+) (%d+)$")
                    if name and textvalue then
                        print(textvalue)
                        local findingplayer = game.Players:FindFirstChild(name)
                        if findingplayer then
                            findingplayer.PlayerGui.CurrencyGUIs.CoinFrame.CoinAmount.Text = textvalue
                        end
                    end
                end
            end)
        end
    end
end)

What I want to do is; To be able to change myself or other players' stats.

The problem is that you have to write out the players full name for example :change HydroDivinity 69

what i want it to be able to do is something like this; :change hy 69 or :change hydr 69 etc
