First, if you are using plugin:

Quote:

What happened to "z", the optional string? z has been removed (you can still use it but will get a server warning) to make way for the new optional parameter system described later on.

so, you need change z to s, like..

new id, string[ 128 ];
sscanf( params, "us[128]", id, string ) ) ...

[128] - lenght of ur string.

and your command can be MUCH longer:

pawn Код:

COMMAND:kick( playerid, params[ ] )
{
    if( PlayerInfo[ playerid ][ pAdminLevel ] == 0 ) return SendClientMessage( playerid, 0xAAAAAAAA, "You are not admin or the required level." );
    new
        ID,
        Reason[ 101 ]
    ;
    if( sscanf( params, "us[101]", ID, Reason ) ) return SendClientMessage( playerid, 0xFFFFFFFF, "/kick [playerid/name] [reason]" );
    if( ID == INVALID_PLAYER_ID || ID == playerid ) return SendClientMessage( playerid, 0xFFFFFFFF, "This player is not connected" );
    if( strlen( Reason ) > 100 ) return SendClientMessage( playerid, 0xFFFFFFFF, "Reason is too long.. [Max chars - 100]" );
    new
        String[ 188 ]
    ;
    format( String, 188, "Admin %s kicked kicked %s. | Reason: %s", GetPlayerNameEx( playerid ), GetPlayerNameEx( ID ), Reason );
    SendClientMessageToAll( 0xFFFFFFFF, String );
    Kick( ID );
    return true;
}
