PHP код:

if(InDM[playerid] == 1)
{
new aName[MAX_PLAYER_NAME], string2[128];
GetPlayerName(playerid, aName,sizeof(aName));
format(string2,sizeof(string2),"[DM] %s[%i] : {FFFFFF}%s",aName,playerid,text);
printf(string2);
SendClientMessageToAll(GetPlayerColor(playerid),string2);
return 0;
} 


This should work.
You simple trying to access the array from enum, which is not in the enum :/
Just use

PHP код:

InDM[playerid] = value 


instead of using PlayerInfo enum :/
