Obtain values from selected row from other widget

Hi again,

Basically I have a page with 3 widget, lets say A, B, and C. B is an action button widget with “Select By” from widget A. Widget C stands alone. I already put a running UpdateRecord that triggered by the action button in widget B, but can only use the information/data from widget A, to update records also in widget A.

What I need is being able to grab a value from selected record in widget C and UpdateRecord it into widget A.

Please kindly need your help.
