Try this:

Код:

CMD:stats(playerid, params[])
{
	new giveid;
	if(!sscanf(params, "u", giveid))
	{
		if(IsPlayerConnected(giveid))
		{
			ShowPlayerDialog(playerid, 4, DIALOG_STYLE_MSGBOX, "{D1D1D1}Player Stats", ShowStats(giveid), "Ok", "");
		}
		else { SendClientMessage(playerid, red, "ERROR: Player not connected!"); }
	}
	else { ShowPlayerDialog(playerid, 3, DIALOG_STYLE_MSGBOX, "{D1D1D1}Player Stats", ShowStats(playerid), "Ok", ""); }
	return 1;
}

If the problem is still not solved with the command I gave you, then it's probably a too big string which shows the stats.
