I was playing with filtering content using views but seems I can't make them work the way I want : to display the articles of an edition based on the latest issue no. (or latest issue date) on the frontpage. I figure out this can be done using contextual filter but don't know how.

My content types are:

editions: edition_no, edition_date, edition_title article: title, body, edition_no.

Many thanks for help.
