[Need help creating a report]

I preface this with the comment that I know little about managing databases.

I have a custom field that I use to identify what box each book is in. I want to run a report that shows me

1) how may books are in each box

2) what books are in each box

Is that possible?

That worked. It didn't pull through what I renamed the column but it looks like it pulled through the data. 

 

Thanks!

[Upgraded - Lost Custom Fields]

I haven't been in the system for over a year. One of my projects for 2021 is to downsize my collection. As my license for last year expired I upgraded yesterday, downloaded the update, and converted my database.

When I inventoried everything I had 2 years ago I created a Custom Field for Box Number. Both that label and any custom field data data I had are now completely gone.
