Why will this teleport players that arent matching to string.match? (ty if you help <3)

Im trying to teleport a player to a part, and when I say "/r .. players name here" it will teleport a random player, and not the player I was looking for. I'm using string.match, and it keeps teleporting random players. I think it is because string.match only matches 1 letter, idk. Help pls ty <3 (no homo)

game.Players.PlayerAdded:Connect(function(player)
    local source = string.upper(player.Name)
    if Check(source) == true then
        player.Chatted:Connect(function(msg)
            if string.match(string.lower(msg), command) then
                local Players = game.Players:GetPlayers()
                for i = 1, #Players do
                    local strFind = string.find(string.lower(msg), command)
                    local plrName = strFind + 2 or strFind + 1
                    if strFind then
                        if string.match(string.sub(string.lower(msg), plrName), string.sub(string.lower(Players[i].Name), 1, string.len(plrName))) then
                            TeleportPlayer(Players[i].Name)
                            return true
                        end
                    end
                end
            end
        end)
    end
end)
