<p>I have a script and a report layout that contains a field X, a sum aggregation based on x and another aggregation based on the first one. They are made on 2 different groups. So when I run the report from maximo if the parameter is wrong i receive some data binding errors for the last aggregation. If I remove it, is working. Is there any condition to not calculate a field if another one is null, or to break the report if the parameter is wrong, even if I don't have a list with the correct ones?</p>
