Auto select in repeating table - InfoPath 2013

Hi All

I've created a repeating table in my InfoPath form. There are 7 columns. One particular column have drop down list option.

Status (Drop down list) - options (Pending, Processing, Completed)

Completed By - current user

Completed Date - today's date

I want "Completed By" and "Completed Date" to auto populate information as above when I select 'Completed' in the "Status" column.

I set as below but it doesn't work. Please guide. Very Urgent!!!
