In pawno i have this : public OnPlayerPrivmsg(playerid, receiverid, text[])
{
if(Mute[playerid] == 1) return 0;
PlayerRespond [receiverid] = playerid;

new pname[MAX_PLAYER_NAME];
new rname[MAX_PLAYER_NAME];
new tmpstring[256];
GetPlayerName(receiverid,rname,sizeof(rname));
GetPlayerName(playerid,pname,sizeof(pname));
format(tmpstring,sizeof(tmpstring),"to %s(%d): %s",rname,receiverid,text);
SendClientMessage(playerid,0xFFCC22FF,tmpstring);
format(tmpstring,sizeof(tmpstring),"from %s(%d): %s",pname,playerid,text);
SendClientMessage(receiverid,0xFFFF22FF,tmpstring) ;
//Above return 1
return 1;
}
