I have a Google Sheet which updates automatically from a Google Form, the most recent entries appearing as a new row at the bottom. Additionally, I have another Zap posting the most recent row as a Slack message. I want one of the columns in my sheet to contain a formula, but if I drag the formula all the way down into currently empty rows, the Zap that posts to Slack won’t work.
To get around this, I’m trying to make my new Zap find the most recently updated row in the sheet, and fill in the correct cell with the formula (which also has to reference the recently-created row). All the steps look fine, until I test the action and get the error message in the title. I’m sure that the form is updating to the sheet correctly, and Zapier is able to find the row I want to edit correctly. Anyone have any ideas why I could be getting this error? Thanks.
