I did put the size after the enums.

pawn Code:

enum P_INFO {
    pName[24], 
    pPass[MAXPSIZE], // MAXPSIZE == 16
}

INI_String("Name", PlayerInfo[playerid][pName]);
INI_String("Password", PlayerInfo[playerid][pPass]);

error 017: undefined symbol "INI_String"
error 017: undefined symbol "INI_String"
