try to use this:

pawn Код:

tmp = strtok(cmdtext,idx);
            if(!strlen(tmp))
            {
                SendClientMessage(playerid, LIGHTBLUE2, "Usage: /mute[PlayerID]");
                SendClientMessage(playerid, orange, "Function: Mutes a player");
                return 1;
            }
            target = ReturnUser(tmp);

or the most fastest way sscanf

pawn Код:

CMD:mute(playerid, params[])
{
     new target;
     if(sscanf(params, "u", target)) return SendClientMessage(playerid, red, "Usage:/mute [ID]");
//do your cmd here
     return 1;
}
