Hi there! I didn’t understand your question.

Would you be able to write it natively in your language and then use google translate? Perhaps that would clear any confusion.

in report table
i want formula to clalculate all set items if set items is blank

Data.Filter(Project=thisRow.Projectand [Set items]=thisRow.[Set items]).Value.Sum()

if set items is blank
select all set items in the project for selected project

in report table
third row project is selected but set items not selected i want formula to calculate all set items and return 80 instead of 0
