<p>Hi all, I am working on a Birt report that requires me to grab aggregated values from a child table to be used as part of a calculation in the parent table. I tried using variables to grab the values but it doesn't work as intended. The variables does not update itself with the aggregated values from the child set immediately.</p>
<p> </p>
<p>Is there any way to do this?</p>
<p> </p>
<p>Any help will be much appreciated.</p>
