pawn Код:

if(!IsPlayerAdmin(playerid)) == 0)

better remove the == 0
and fail it checks if player is not logged as rcon administrator.

you could just do

pawn Код:

if(!IsPlayerAdmin(playerid))

checks if player is not admin, if player is admin this function will not called

plus bad indentation

hope you read this!
2/10

EDIT:

also this one is fail

pawn Код:

if(playerid == id)

Are you crazy? did you copy/paste this from other?

this is the correct one

pawn Код:

if(id == playerid)

checks if the selected id is playerid. really really bad tutorial plus
you could just do

pawn Код:

if(id == INVALID_PLAYER_ID)

instead of IsPlayerConnected. sscanf supports what i give above ^^^
