When i have this, its like it doesnt minuses the ebill, and tax, but it will plus it to the netpay, what is wrong with my code?

pawn Код:

new donatorbonus;
        if(PlayerInfo[playerid][pDonatorLevel] == 1) { donatorbonus = 3000; }
        else if(PlayerInfo[playerid][pDonatorLevel] == 2) { donatorbonus = 6000; }
        else if(PlayerInfo[playerid][pDonatorLevel] == 3) { donatorbonus = 9000; }
        new netpay = checks += donatorbonus += interest -= storagefee -= TaxValue -= PlayerInfo[playerid][pSock] -= ebill;
