ServiceNow List Field Type: Displaying Values in Email Notifications

Displaying List Field Type Values in Email Scripts

When trying to display values from a List field in an email script you can’t simply display the field name from the form.

Here’s my specific work example:

I created a List field type called “Sizes Needed” (u_sizes_needed) in a form used to submit a marketing request.

This List type field references a custom table that has a single custom field called size (see Figure 1).

I needed to display in an email to the Marketing department AND to the requester all the sizes the requester selected in the form. NOTE: that when you view a previously-submitted form, ServiceNow automatically converts this to a comma-separate text string. I expected this to happen when I was working in my email script, but what I got was a comma-separate string of sys_ids and not the associated values. So I needed to do a GlideRecord on this custom sizes table then cycle through the values I found to get their associated display name.

Here’s how I did it. I use a notification email script because I’m getting and displaying the values in two separate emails – one to the requester and one to the marketing team.

First here’s the wrong way:

If (current.u_sizes_needed !== “”) {

template.print(“<br />Sizes Needed: ” + current.u_sizes_needed);


This produces something like this in the email:

Sizes Needed: 597267290f434b00d3a3590be1050e67, 597267290f434b00d3a3590be1050322,597267290f434b00d3a3590be1043391

Well that’s just not going to work for either the requester or marketing – so here’s how I got it to work.

  1. I do a GlideRecord query on the custom table
  2. I use the available “IN” javascript operator that comes with the GlideRecord object ( — scroll down to the Available JavaScript operators section).
  3. I cycle through all the selections that are found, then get the associated field value in that table that I want (I this case I wanted the ‘size’ field value from the custom table).
  4. I add each to an existing variable.
  5. I use the template.print() method to print the variable’s contents into the email body.

if (current.u_sizes_needed !== “”) {

var sizes_to_display = “”;
var selected_sizes = new GlideRecord(‘x_goaz_marcom_marketing_communications_request_print_sizes’);
selected_sizes.addQuery(‘sys_id’, ‘IN’, current.u_sizes_needed);
while( ) {

sizes_to_display += “<br /> — ” + selected_sizes.size;


template.print(“<br /><br />Sizes Needed: ” + sizes_to_display);

So in the email that marketing and the requester receives, if they select size options, they are listed like this:

Sizes Needed:

— Full Size
— Diecut
