Problem with personalization using supplemental table

Hi all

I am trying to do a personalization with a supplemental table but I get the following error: "Error personalizing field: SUPP.COUNTRY: empty field value"

I did the following:

- I made a supplemental table with a DEK with the same name that a field in the Profile List.

- I added both tables in the Data Sources of campaign.

- I added fields of supplemental table using message designer.

I attached captures to show my problem.

How I can get the personalization with a supplemental table?

What I am doing wrong?

What step I am forgotting to do?

Thanks

Cristian
