Because they do not exist. I told you to search for "OnMapUpdate" only (without the quotes "" of course).

pawn Код:

SetTimer(funcname[], interval, repeating);

was an example of the parameters of the SetTimer.

pawn Код:

SetTimer("OnMapUpdate", 1000, true);

is the correct one which calls OnMapUpdate every second. You'll need to find where you set the timer about OnMapUpdate in your script and replace it with the above code.
