[Whizion]

This is a multiple parameter command, and i have some trouble with her:

pawn Код:

cmd(pm, playerid, params[]) // PM Command.
{
    if(IsPlayerConnected(playerid))
    {
        new pl, opt[16], msg[64], str[128];
        if(sscanf(params, "s[16]", opt))
        {
            SendClientMessage(playerid,COLOR_HELP,"USAGE: /pm [location/message/stop]");
            return 1;
        }
        if(!strcmp(opt, "location", true)) // Sends a player your location.
        {
            if(sscanf(params, "s[16]u", opt, pl))
            {
                SendClientMessage(playerid,COLOR_HELP,"USAGE: /pm [location/message/stop] [ID/PartOfName]");
                return 1;
            }
            if(GetPVarInt(pl, "StopPM") == 0)
            {
                new Float:px, Float:py, Float:pz;
                GetPlayerPos(playerid, px, py, pz);
                SetPlayerCheckpoint(pl, px, py, pz, 5.0);
                format(str, sizeof(str), "PM: %s has PM-ed you his location. He's marked RED on your radar.", PlayerName[playerid]);
                SendClientMessage(pl, COLOR_RED, str);
            }
            else { SendClientMessage(playerid,COLOR_ERROR,"ERROR: This person has blocked PM's."); }
        }
        else if(!strcmp(opt, "message", true)) // Sends a message to a player.
        {
            if(sscanf(params, "s[16]us[64]", opt, pl, msg))
            {
                SendClientMessage(playerid,COLOR_HELP,"USAGE: /pm [location/message/stop] [ID/PartOfName] [message]");
                return 1;
            }
            if(GetPVarInt(pl, "StopPM") == 0)
            {
                format(str, sizeof(str), "PM: %s says: %s.", PlayerName[playerid], msg);
                SendClientMessage(pl, COLOR_RED, str);
            }
            else { SendClientMessage(playerid,COLOR_ERROR,"ERROR: This person has blocked PM's."); }
        }
        else if(!strcmp(opt, "stop", true)) // Stops PM's from being send to you.
        {
            if(GetPVarInt(playerid, "StopPM") > 0) { SetPVarInt(playerid, "StopPM", 0); SendClientMessage(playerid,COLOR_GREEN,"INFO: PM's Activated."); }
            else { SetPVarInt(playerid, "StopPM", 1); SendClientMessage(playerid,COLOR_RED,"INFO: PM's Blocked."); }
        }
    }
    return 1;
}

It should be like this:

You type: /pm location whizion - and it sends your location to a player named whizion (but it doesn't do nothing).

You type: /pm message whizion yo sup' - and it sends a PM with text: you sup' to a player named whizion (but it doesn't do nothing).

The only thing that's working is /pm stop, but that's really useless if other things don't work.

What am i doing wrong here? Please help, thanks.
