I have already made several basic apps and feel like I have a pretty good understanding of how to use computed columns. That being said, I can’t figure out why the information inside a lookup column that I created isn’t available to me for use inside a “basic table” component. I’m able to select from all of the other columns in that sheet but the lookup columns aren’t showing up.

Am I missing something? I feel like I have done this same thing before and it has worked.

Thanks!

JB

Is your lookup returning a single value or an array?

You can tell by examining it in the data editor. If the value is inside a bubble, that means it’s an array and can’t be used as the source of a single value component.

The most common mistake with this is a lookup via a multiple relation instead of a single relation.
