In a custom defined DFF, how to populate dynamic values specific to Qualifications page

Content

When we navigate to 'Manage Qualifications' page, under edit additional information
We have to define one DFF field
1) Here, we need the value from the response tab, that should get multiplied with 2080

The issue we are facing is dynamic values are getting populated instead of the value pertaining to specific supplier.

For better understanding, please go through the attached document.

We are trying to achieve this using below sql query in the value set.
But it's not working. (More than one value is getting populated. Please refer to the attachment provided.)

select
(pqrv.RESPONSE_VALUE_NUM*2080) abc
FROM
FUSION.POQ_QUESTIONS pq
