Hi there,
I'm trying to create a rule to sum up at Epic level "Venituri totale proiecte depuse €" (customfield_10099) all custom fields (customfield_10090) from all child issues (stories, tasks and especially stories sub-tasks) every time "Valoare factura €" (customfield_10092) changes.

This is what I managed to build so far but it doesn't work.

Any suggestions?
