That’s not the error message, those are just instructions. The error message is simply the word #ERROR.

The problem is that Airtable can’t encode a lookup field, because a lookup field is an array instead of a text string.

In your formula, you can force-convert the lookup field into a text string by adding
& ""
after the name of the lookup field (after the closing curly bracket that surrounds the field name).
