【问题描述】：
标题说明了一切。当我运行代码时，在第 139 行，bankMoney 值变为 NaN 而不是数字。我很确定问题出在我定义一个改变值的值的函数中。这些将是payDay、intrest 或propertyIncome。
如果有人可以帮助我，我会非常感激，因为我整天都在处理这段代码，而这个错误阻止了我继续编码。
我知道我在随机位置定义了很多变量，如果有人决定用机器或手动修复这个问题，我希望我能拥有编辑后的代码，但这不是必需的，因为它不是我的问题。
代码是：
var intrest = function(intrest) {
if(bankMoney > 0) {
positiveIncome(0)
}
if(bankMoney < 0) {
negativeIncome(0)
}
}
var age = prompt("How old do you want your character to be? (Will be randomized if not between 20 and 100.)")
if(age > 100) {
age = Math.floor((Math.random()*81) +20)
}
else if(age < 20) {
age = Math.floor((Math.random()*81) +20)
}
var randomVariable1 = " Years old"
var randomVariable2 = " Press 'OK' if you like this age, or 'Cancel' to have it randomized."
var ageConfirm = confirm("Your character is now " +age +randomVariable1 +randomVariable2)
if(ageConfirm === true) {}
else {
age = Math.floor((Math.random()*81) +20)
}
confirm("Your character is now " +age +randomVariable1)
var salary = 10000
var bankMoney = 120000
var bank = prompt("choice a bank. (Put in the number, not the name.) (You only get to do this once, so choose carefully. 1. A&A Positive income: 10% Negative income: 25% 2.

if(bank < 1) {
Math.floor((Math.random()*4)+1)
}
if(bank > 4) {
Math.floor((Math.random()*4)+1)
}
if(bank === 1) {
function positiveIncome(positiveincome) {
bankMoney = bankMoney + (bankMoney * 0.1)
}
function negativeIncome(negativeincome) {

}
