I have a view that displays, let's say, videos that each user has added. This view is shown in their profile. I'd like to use fields from their profile as the title of the view. Specifically, fields containing their first and last name. So for instance, I'd like the title to be "Ashton Kutcher's Videos."
I know that you can use arguments to alter the title of a view, but I can't seem to find a way to use the content of fields.
Additionally, because of a silly decision when building the site, I did not require users to enter their names. Therefore, sometimes I will need to display their username instead of their first and last names, conditionally.
