How to get information from an existing record in a Person Profile Certification section?

Summary:

Hello,

we are trying to make an autocomplete rule that allows to add/modify a new certificate based on the information from an existing certificate. We tried to use rowvarset to get and read the rows in the "Gestione Legame Supervisore Test su Certification" section in Skill and Qualifications but the problem is it seems the rule can't read the information from an existing/previous record and for that reason we can't make a condition.

For example: We need to make a rule that allows to add a new certificate if the Expiration Date of the Certificate "Abilitazione 2" is already surpassed.
