Automation rule to roll of sum of size field to parent is failing

[Abhiudaya Pratyush]

I have created two custom fields size and complexity, product of the two is stored in story point field.

Please note all three are custom fields, accumulation is happening for story point field, but not for size field and complexity field.

Hi @Abhiudaya Pratyush 

Can you share the rule that you have, and the audit log where it is failing?
