It looks like your "Revenue AVIDZ" column is a Lookup to a linked table. If I'm seeing correctly you should be able to switch "Total Revenue" to be a Rollup to the same field and set it to sum. Your names will be different than this example, but hopefully it will help.

I have now strong faith on Airtable community just because of people like you!
Thanks a lot man. Much appreciated!
