How to extract subtable entry

I have a subtable in a customer contact form. The first entry is a selection to choose the user, the next is the entry date and so on.
How do i extract the name of the last user so it can be displayed on the Listing page next to the customer enquiry. If i select the user header is just pulls the column full of user names rather than the last one.

Any help accepted :slight_smile:

Have you tried a formula LAST(subtable header) which gives you the last value in the list.
