It should look like this:
On the top:

pawn Код:

new IsPlayerSuspected[MAX_PLAYERS];

pawn Код:

forward Suspecter(playerid);
public Suspecter(playerid)
{
    IsPlayerSuspected[playerid] = 1;
}

And when you call the function , I mean when you suspect him , when you click on him like this:

pawn Код:

Suspecter(externalplayerid[playerid]);
