Cant use Lookup table hosted in Dataverse in the Gallery

(0) ShareShare

Posted on by 8

Hi,

I have two tables, Books and Library respectively.

The library table has a Book ID column that is a lookup column and references to the Books table. 

I added a gallery control in the app and attached it to the datasource "Library".

When i try adding the Book ID column from the Library table (which references to Books column originally). The gallery does not populate anything.

 

I have tried using this.

LookUp(Books,ISBN=ThisItem.'Book ID',Author)

Any help would be appreciated.
