[Logic_]

PHP код:

public OnPlayerEnterCheckpoint(playerid) 
{
    if(playerid != INVALID_PLAYER_ID)
    {
        new text[128]; 
        if(IsCapturing[playerid][usapro] == 1) 
        {
            if(IsPlayerInVehicle(playerid, usapro)) 
            {
                DisablePlayerCheckpoint(playerid); 
                IsCapturing[playerid][usapro] = 0; 
                format(text, sizeof(text), "~r~%s~w~ has Captured ~r~USA prototype ~w~for his team!", pName(playerid));
                RemovePlayerFromVehicle(playerid); 
                SCM(playerid, C_GREEN, "Congratulations! You got +6 score and +6000 cash!");
                GivePlayerMoney(playerid, 6000); 
                SetVehicleToRespawn(usapro);
                SetPlayerScore(playerid, GetPlayerScore(playerid)+6); 
                TogglePlayerAllDynamicCPs(playerid, 1); 
                TextStats(playerid);
                Savestatus(playerid); 
            } 
            else 
            {
                DisablePlayerCheckpoint(playerid); 
                SCM(playerid, RED, "You're not in the USA Prototype."); 
            }
        }
    }
}
.... 


Would be better if you use switch statements.
