How to get names/email address from List Collector for email notification

[KayB2]

How do I get the email address of user from List Collector so I can send email notification to them via Workflow?

I tried this script but not working. Please help! 

//I named my list collector field choose_name

answer = [];
var user = current.variables.choose_name.split(',');
for (var i = 0; i < user.length; i++) {
var u = new GlideRecord('sys_user');
if (u.get(user[i])) {
answer.push = email.addAddress("user", u.email, u.getDisplayValue());

Hello Ankur, 

Looks like variable value is not coming. gs.log result is undefined. Please see below.

I tried adding toString() to the var user and it looks like value(sys id) is coming. However, no emails were sent. 
Please see below snips.

Hello Ankur,

Good news! 

I replace emailSysId.push with answer.push(last line of script) and it works!

Emails are now being sent to all users selected from the List Collector. Fantastic! 

Thank you very much for helping me out! 

Regards,
Kay

Used this in Madrid and worked perfectly, the only modification necessary was adding .toString() to the var user=
THANK YOU

answer = [];

var emailSysId = [];
var user = current.variables.choose_name.toString().split(',');
gs.info("Users from variable are:"+user);
for (var i = 0; i < user.length; i++) {
var u = new GlideRecord('sys_user');

if (u.get(user[i])) {

emailSysId.push(u.sys_id.toString());

}

}

answer = emailSysId;
