I have the following code:

```
var MonthsInStartYear = (12 - startMonth) + 1;
var MonthsInEndYear = (12 - endMonth) +1;
var show12Month = MonthsInStartYear + MonthsInEndYear ;

if(MonthsInStartYear < 12) {
  alert("Months in Start Year: " + MonthsInStartYear);

  //check the number of Months for endDate
  if(MonthsInEndYear < 12) {
    alert("Months in Start Year: " + MonthsInEndYear);

    //proceed if total is within 12 months
    if(Number(show12Month) <= 12) {
      alert("hahahaha");
    }
  }
}

```

The problem is that `alert("hahahaha");` is not executing. What went wrong?
