AppSheet Formula not Updating in App or Google Sheet

[EPP_Recycling]

Good morning AppSheet Community,

I am encountering a problem with my AppSheet Formula. This formula adds the sums of two columns from another table. AppSheet says that the formula works, however, the data is not updating in the app or the google sheet. I have tried to make the formula an initial value, but that did not work either.

Can anyone help?
Thanks
