Hi Andrey and thk for the reply,
Scenario: 1 visit with 3 entries.
I have a table with 3 segments:

Visitor B, within same visit, enter to the site with 3 different channels, so I have 3 entries but only 1 visit.
In order to determine the number of visits of a particular segment (and decuple it) I use Entries with hit number = 1.By this way I can count the number of first entries.
However, it seems that i cannot know what happens withing this entry. I would like to know what happens in the first entry (pageviews, product bought, exit page etc.)
