Generate report with data from a list

Hi! im diving into the world of Generate report, and i cant find a way to show as a filter the data i have in an attribute, i proceed to explain it :

I have added the “thickness” (spessore) attribute to my DC, as so, to calculate the weight, as follows:


so that as i select the Thickness i can calculate the weight with this proceedure:


so far so good,

The problem is, when i when i Generate report, and i select the Filter : dyc:Spessore, i come out with the data of “0.690…0.790…” etc, and i dont want that, i want it to show the selection : T 1.0…T1.2, Etc

What am i doing wrong?

use an attribute Spessore2


I worked! I would give you a hug.
