Thank you to both Paul and Birkir. We are going to play with the code. I got it by simply going to the view and getting the source.

We might have more questions before our meeting tomorrow.

This is actually the recommended way to present the status role, where one element on a page updates in response to changes in other elements on the page.
Tehre are a few drawbacks:
role="status" does not work so well for Jaws unfortunately.
aria-labelledby, while semantically valid, is not going to be announced by most screen readers, because usually aria-labelledby or aria-label are not considered to be used on divs or spans without a specific role.

For the output span I would put it inside a div, and put aria-live="polite" and aria-atomic="true" on it

<div aria-live="polite" aria-atomic="true" role="region"
aria-labelledby="Result">
<span id="sumLabel">Sum: </span>
<span id="outputId"> </span>
</div>

This is just from quickly glancing over the code, not testing it.
