Hi @Michael_Leidensdorf ,

you have to change your data structure by using one field (column) for week1, week 2, and progression of followers separately. The last field with be a function that runs the calculation.

Does it work for you ?

Thanks

Airtable does not handle running totals well. If you only want the difference, you can link each record to its predecessor and calculate the difference. However, that is a lot of linked relationships to maintain. You can also use a script to calculate a running total. There is an example script in the docs.
