For looping through an Array for an input form

I am trying to for loop my array which contains a couple of variables I created for a input form project. I believe my coding is correct, however, the data is not populating on the form at all. any clues?

var age = parseInt(document.getElementById("postAge").value);
var phoneNumber = parseInt(document.getElementById("postPhoneNumber").value);

var numberArray = [age, phoneNumber];
for(var i = 0; i < numberArray.length; i++);{
    if(numberArray[i] <= 100){
        document.getElementById("postAge").innerHTML = "Age: " + age;
    }
     else if(numberArray[i] > 100){
        document.getElementById("postPhoneNumber").innerHTML = "Phone Number: " + phoneNumber;
    }
}
