value from one table to put in another table

[Fa1con74]

Hello,

I have a form that fills in a “Building” table and in this table I have a field that should be filled in after completing another “Ebras” form that opens at the end of the first one. I would like the “Final Classification” field of my “Ebras” form to be included in my “Building” form in the “Classification” field
Here is a screenshot of my “Classification” field

But it doesn’t work

Hello,

Your expression returns a List, not a single value. What you need is a dereference expression, something like: [Ebras ID].[Classification finale]
