Javascript won't get value from textbox issue, why not?

I have this code: 

<script>
    function getAge() {
        var birthdate = document.getElementById("birthdatebox").value;
        document.getElementById("agecomputed").innerHTML = calculateAge2(birthdate);

    }
</script>

and 

<input type="text" name="birthdatebox" />
        <button onclick="getAge()" name="birthdatebutton">Get Your Age</button>
        <div id="agecomputed"></div>

It should return the calculated value. Nothing happens. Just doesn't work. Please help.

UPDATE: I have a reference to the js file, which contains the calculateAge2 function and it does work when I pass a number directly instead of birthdate variable.

You need to add the id attribute to your <input> element, like this...

<input type="text" name="birthdatebox" id="birthdatebox" />
