Import Data from Excel sheet

I have several records (list of donors) in an Excel file, and I’d like to add/import this data (I have only one fild) into Activity Info, but here’s the message I’m getting please could you advise.
The data matches, but apparently I need to provide additional required information.

Hello Francis,

Sorry you’re having trouble with the import! I’m guessing that you are trying to import into a form that references another form. Even though you have added the values for the one field that exists in the form you are importing into, you must be sure to include columns corresponding to the Key fields in the referenced form. These are the required fields you see on the right-side panel. You can read more about this here: Troubleshooting importer-related issues

By the way, do you need some support with an HPC-specific workflow? If so, I can connect you with the relevant contacts.
