Javascript onclick not firing

Question

I have a really simple javascript function to return the index of a selected field, it looks like this:

function validateForm() { 
    alert(document.getElementByID('textfieldAmount').selectedIndex);
    return false;
}

This is called from an input button onClick like this:

onclick="return validateForm();"

but the Javascript is never called and the page is submitted anyway.

If i change the alert to alert("wibble"); the alert works fine and the page is not submitted.

The element i am querying looks like this:

<select name="textfieldAmount" id="textfieldAmount" class="form">

Any ideas why its not working before i kill myself?

javascript is case-sensitive:

alert(document.getElementById('textfieldAmount').selectedIndex);

specifically: ID should be `Id'
