Couldn't find how to sum two data items.

index.php/fa/6787/0/

Maybe I can do it using Name or Element ID?
Thanks.

It's impossible in BIRT to get element value using its name or id?

This is a very difficult task, or Birt is not designed to calculate the sum of two items?

Just use a data item and add the two. See attached example.
row["Aggregation"]+row["Aggregation_1"]

Thank you very much. It seems now I understand how it works. I should use Binding.
