Hi all!

We are looking to add (and see) a custom numeric field to Skills and Qualifications from a custom Content Type. We can see all fields that we managed from Manage Profile Types/Person/Identidad y Misión (our custom Content Type).

The question is: How can we get automatically the introduced numeric value in "Valor (Puntos)" in the content Item, as we get the Name of the Items? 

In other words: We want to add one Skill, and see automatically in the custom numeric field "Valor (Puntos)" the introduced value in the Content Item. Remember: This field has been managed in the Content Type previously.
