Hi there,
I'm pretty new to Airtable so forgive me if the answer is straightforward.
I'm trying to set up the following automation: When an entry in table B has Field A = X and Field B = Y then update Table A, Record Z, in Field "Dernier numéro de facture" by changing its value to {Dernier numéro de facture} + 1 (so incrementing its value by 1)
What should I enter in the Field highlighted in the image attached? I tried {Dernier numéro de facture} + 1 but it outputs a "Could Not parse number" error although last invoice number field is a # Number.
Thanks!
