Flow script that adds to a flow variable value in a "For each item in" action

[Bidduam]

So I have a flow that is ultimately looking up a group, that bit is working and I can see in the flow that it goes through and finds all records, and gets quite a bit of information about each user.

For an email I need to show all members of the group - simply just want the get the display name.

I have a flow variable I've called:

Label: Members List

Name: members_list

Type: string

I have a action in the flow "For each item in group"

Then I have a "Set Flow Variables" with the following script:

var currentList = fd_data.flow_var.members_list || "";

var displayName = fd_data._2__look_up_group_members.group_members.displayName;

if (currentList) {
    currentList += ", " + displayName;
} else {
    currentList = displayName;
}

fd_data.flow_var.members_list = currentList;

The value of members_list is coming back blank.

Anyone know what is missing?
