If the sheet name you’re trying to pull info from doesn’t have a space in it, you can leave out the quotes for the Notes column. So for example, I have a sheet called “Utilities” that I pull budget info from. In my Notes column for that line item, I have Utilities!AF4:AQ5. With the Frequency set to “ExternalSource” it then pulls in the data from that range, and any changes on the Utilities sheet are reflected in my budget items. If it’s still not working, you might try the beta version to see if you have better luck there.
