update field with latest comments

I'm having difficulty updating the field of a view from one section to another.

I would like to update the latest comment information to another field location.
e.g : I have comments 10 of them  but in field Y of different view I would like to see the latest comment updated 

day 1 = Comment 1  field Y  = Comment 1
day 2 = Comment 1 field Y  = Comment 1
day 3= Comment 2 field Y = Comment 2 

When ever I update a new comment - Task Comment section must be updated dynamically.
