Есть код калькулятора btc/usd, eth/usd итд, нужно добавить функцию подсчета при выборе EUR, GBP из селекта D2

<script language="JavaScript">

var nOutsPer1Inc = 6600/1.000; /*RATE*/

function Incsel(obj) /*select  name="D1" RATE*/

	      {
  nOutsPer1Inc = {1 : 6600/1 ,2: 233/1,3: 667/1,4: 277/1}[obj.value]

   if (document.all.am == null)
        return;

    var incSum = document.all.am.value.replace(",",".");
    if (isNaN(incSum))
        incSum = "0";

    incSum = Math.round(incSum * nIncPower) / nIncPower;

    var v = Math.floor((incSum * nOutsPer1Inc - nOutAddon) * nOutPower +
