Probably define AdminLabel this way :

Код:

AdminLabel[MAX_PLAYERS]; 
AdminLabel[playerid] = Create3DTextLabel("ADMIN ON DUTY\nDO NOT ATTACK",0x33DD1100,0.0, 0.0, 0.0, 40.0, 0, 0);
Delete3DTextLabel(AdminLabel[playerid]);

Edit : use print("line ( 1 , 2 ... n )") in multiple lines to see when the code ends.

Edit 2: after reading it well, I saw the flaw and its that you don't return after going on duty offduty
what you code does is :
if ( off duty )
set duty on ( you should just return 1 here )
if ( on duty )
set duty off. ( same thing )
