remove one of the comma separated values in a cell while placing row data into variable

remove one of the comma separated values in a cell while placing row data into variable

Hi all

I am working through the tutorials here:

I have modified the table so it has 3 columns.

I am now able to collect the row data into a variable
Eagle 2018-09-25 12:00,1537876800 predator
But I would like only the UnixTimeStamp (eg 1537876800) value of t comma separated datetime value cell in my final variable like so :
Eagle 1537876800 predator

How and when should this be done ? (During the element scan or after?)

Also not sure I keep getting an úndefined' message after adding a few rows then removing them.

As always I would appreciate any help or advice.
