This one need zcmd and sscanf:

pawn Код:

CMD:setskin(playerid, params[]) 
{
    new level, id;
    if(sscanf(params, "dd", id, level)) return SendClientMessage(playerid, WHITE, "{FF0000}USAGE:{FFFFFF}  /setskin [playerid] [skin id]");
    {
        if(level > 299 || level < 1) return SendClientMessage(playerid, GREY, "Invalid skin ID!");
        SetPlayerSkin(id, level);
    }
    return 1;
}
