SUM of a Calculated value
<p>I have been working on a query that I can't seem to fix;
I need to return a total value of Fees for this table</p>

<pre><code>ID | somevalue | month
xx | 33        | 3
xx | 33        | 3
</code></pre>

<p>I need to put out '66', grouped by month - however as the somevalue field is calculated how would I go about summing it?</p>
