You have to change aAdmin to pAdmin

PHP код:

enum aInfo 
{ 
    aAdmin 
} 
new PlayerInfo[MAX_PLAYERS][aInfo]; 


Can you try with that? (This is the same that @n00blek gave you, I just corrected it)

PHP код:

enum aInfo 
{ 
    pAdmin 
} 
new PlayerInfo[MAX_PLAYERS][aInfo]; 


EDIT: Oh sorry, on other hand, you can simply change this :

PHP код:

switch(PlayerInfo[playerid][pAdmin]) 


- >

PHP код:

switch(PlayerInfo[playerid][aAdmin])
