cmd:help(playerid, params[]) // also possible to use CMD and COMMAND 
{ 
    if( MONEY[ playerid ] < 500 )
{
 return SendClientMessage(playerid...);
}
    return 1; 
}

so sendclientmessage return can 1 or 0, of course player can't be not connecting when writing command, but still i just care it's matter what return you write it's anything do to command or that don't care.
