As you can see in the image bellow, the data is sent to the next row of execution instead of the current item:

The right most fields are doing a sum (Soma=Sum) of the green and red fields respectivelly.
I have already tried everything i know to make it show the sum properly, used a big panel with the small panels inside it, used another panel for the sum, re-creating the sum fields, using variables, everything gives me the same results.
