Convert Numbers to Words in Acrobat Forms

I was able to get this to work for forms using this javascript: Keep in mind that if the field is a number, you need to put the proper input name: Number or String. It will not calculate correctly if it is the wrong input.

var strNumber = Number(this.getField("Field1").value) + 
                Number(this.getField("Field2").value) ;

var nNumber = Number(strNumber);

event.value = ConvertToWords(nNumber);


function ConvertToHundreds(num) {    aTens = ["Twenty", "Thirty", "Forty", "Fifty", "Sixty", "Seventy", "Eighty", "Ninety"];    aOnes = ["Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine",
        "Ten", "Eleven", "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen", "Seventeen",
        "Eighteen", "Nineteen"
    ];

    var cNum, nNum;
    var cWords = "";    num %= 1000;
    if (num > 99) {
        /* Hundreds. */        cNum = String(num);        nNum = Number(cNum.charAt(0));        cWords += aOnes[nNum] + " Hundred";        num %= 100;
        if (num > 0)            cWords += " and "
    }

    if (num > 19) {
        /* Tens. */        cNum = String(num);        nNum = Number(cNum.charAt(0));        cWords += aTens[nNum - 2];        num %= 10;
        if (num > 0)            cWords += "-";
    }
    if (num > 0) {
        /* Ones and teens. */        nNum = Math.floor(num);        cWords += aOnes[nNum];
    }
    return cWords;
}

function ConvertToWords(num) {
    var aUnits = ["Thousand", "Million", "Billion", "Trillion", "Quadrillion"];
    var cWords = (num >= 1 && num < 2) ? "Dollar and " : "Dollars and ";
    var nLeft = Math.floor(num);
    for (var i = 0; nLeft > 0; i++) {
        if (nLeft % 1000 > 0) {
            if (i != 0)                cWords = ConvertToHundreds(nLeft) + " " + aUnits[i - 1] + " " + cWords;
            else                cWords = ConvertToHundreds(nLeft) + " " + cWords;
        }        nLeft = Math.floor(nLeft / 1000);
    }    num = Math.round(num * 100) % 100;
    if (num > 0)        cWords += ConvertToHundreds(num) + " Cents";
    else        cWords += "Zero Cents";
    return cWords;
