Performing Simple Math on a Data(Aggregation) Value?

jdlarkin

<p>First off, I'm very new to BIRT, so if someone can point me in the right direction, I'd be very grateful.</p>
<p> </p>
<p>I have an existing report that I'd like to edit. This report has a table with aggregation (SUM) data in the footer. I'd like to refer to that aggregation data (the summed value) in another part of my report, where I'd like to perform simple math on the summed value (i.e., multiplication between the summed value and a report parameter), and display the results as text.</p>
<p> </p>
<p>I thought to do this by referring to the aggregation data in an expression (JavaScript), but haven't had any luck. Is this the best way to do this, or is there a better way?</p>

<p>I've just learned about binding data, which allows me to do what I need.</p>
