I already have a column with the featured image…I want to pull it and copy it over to another column, but it needs to correlate with the business in the same row.
From your screenshots, I think the relation should be set on the business name/ID rather than the featured image. From that single relation you can pull the name & image over.
OK, based on your other post, I think I now understand what you are trying to do. Looks like you already figured it out? You’re doing a self relation to use and inline list for the circle image, correct? I do the self relation thing quite a bit too. I think the problem was you were using a single relation, and instead needed a multiple relation. The lookup column isn’t necessary in this case as you only need the relation to assign to the inline list.
Do as @ThinhDinh said and use the business name or row ID for the relation instead of the photo. Linking a blank value to every other blank value in the sheet is going to give you several results.
