Using a ConfiForms ListView macro to show the data, "choice1" field followed by "votes" field

Votes

As the voting field holds users who has voted then we can easily list the users who has voted

With the help of Virtual functions, and "asUserNames" in particular. So, using "votes.asUserNames" will show the list of usernames who has voted for this particular "choice"

Who has voted
