I’m making a new spreadsheet to replace my 2023 version, it became too riddled with issues so I’m starting fresh. On the ‘transactions’ tab I have added a ‘group’ column as per the instructions listed here:
The ‘group’ column is able to properly reference the ‘category’ column and the text string is fine. However, I still get the following error message:
-Red triangle in the top right corner of the cell with the note…
-Invalid: Input must fall within specified range
My guess is that you inserted a Transactions sheet column when the Category column was selected, which would copy the Category column data validation rules.
If so, delete the column you added and insert a column elsewhere.
