You cannot format a string inside of SendClientMessage. Use this instead:

pawn Код:

new Float:x, Float:y, Float:z, string[128];
                    GetPlayerPos(playerid, x, y, z);
                    if(IsPlayerInRangeOfPoint(playerid, 10.0, x, y, z))
                    {
                     format(string, sizeof(string), "%s has used their authorization card to open the door.", szPlayerName);
                     SendClientMessage(playerid, COLOR_PURPLE, string);
                    }
                }
            }
