eate three text fields. Name each accordingly, and also
change the attribute of <b>Numeric</b> to "True" for each. This will ensure that only
numbers are entered.</p>

<p>The third and last field, <em>totalfield</em>, we will set <b>Editable</b> to "False" to
keep the user from changing the answer, and also set <b>Underline</b> to "False" so that it
does not confuse them to think they can change it.</p>

<p>Lastly, we will create a button and change the label to "Add!"</p>
