Euler #2 Javascript Error [on hold]

Vote count:

-2

I am new to programming so I may just not understand, but I feel like this code should work, but it returns 0... I tried to keep appending a number while the while loop is running.

var lastNum = prompt('What is your number fair maiden?');
var numbersArray = [1,2];
var total = 0;
var firstNum = 0;
var secondNum = 1;
var numberAppend = 0
while (numbersArray[secondNum] < lastNum) {
    numberAppend = numbersArray[secondNum] + numbersArray[firstNum];
    numbersArray.push(numberAppend);
    if (numberAppend % 2 === 0) {
        total += numberAppend;
    }
    firstNum = 1 + firstNum;
    secondNum = 2 + secondNum;
};

console.log(total);
