Reading subforms values related to specific record from another form

Reading subforms values related to specific record from another form

Hi all,

I have the form A which has a key field "K" and also there's a subform "A.1"

In a different form "B" I need:
1. Select the field K
2. Based on the selected record by the field K, allows me to select in a subform, records from "A.1" subform from A.

This applied should be.

Job candidates are entered on Candidates Form "A" when they register into a job search process. They have an unique name (K key field) and also there's a subform for Job references (A.1)

In form "Reference validation" "B" I need to select the Candidate's name (K) and then in a subform, select the Job reference from a subform which should read the Candidates Job references from A.1.

How can I do this?

Hope to be clear.

Thanks!
