Automatically include attachments from TASK, on Email Client Template

[SammBroadbent]

I found an old discussion but didnt seem to show the answer resolved the issue.

I am wanting to see if its possible to automatically include any attachments from a task, on Email Client Template when opened up from the ellipsis menu.. 

Looking at previous help, they mentioned creating a Notification Email Script with the following code...

var sysID = current.sys_id;

var grAttach=new GlideRecord('sys_attachment');

grAttach.addQuery('table_name','sn_vdr_risk_asmt_task');

grAttach.addQuery('table_sys_id',sysID);

grAttach.query();

while(grAttach.next())

{

template.print ( 'Attachment: <a href="/sys_attachment.do?sys_id=' +grAttach. sys_id + '">' + gr.file_name + '</a>\n ' );

}

but it doesnt work, is there something i've done wrong?
Thanks,
