Help with format of string content

[Bidduam]

I've managed with help to convert list collector values to a string, but I can't seem to get some email addresses to present the way they do to be read in the notification in order to be sent, would love some help please.

So currently the email addresses are being presented as so:

'zxy@email.com', 'abc@email.com', 'plo@email.com'

What I need it to look like is the same thing without the  ' ' around the addresses:

zxy@email.com, abc@email.com, plo@email.com 

The script I have for adding the values to the flow variable is:

var add_list = fd_data.flow_var.add_user_list;

if (add_list == '')
    add_list = '\'' + fd_data._15__look_up_record.record.email.toString()+ '\'';
else
    add_list += ',\'' + fd_data._15__look_up_record.record.email.toString() + '\'';
return add_list

@Bidduam Try the following.

var add_list = fd_data.flow_var.add_user_list;
return add_list.toString();

Using just that doesn't pick up anything at all

@Bidduam Try the following.

var add_list = fd_data._15__look_up_record.record.email.toString();
return add_list;

if it's an array then it will always be in that format.

please share the complete details and screenshots.
