amr users like me not filtering

Hi.
I am using arm users with three add-ons (plus, cimy and users like me).
I have created a users list (#5) which I want to use to show the users living in the same town as the logged in user.
I have made changes accordingly in the add-on 3 lines :
/if (!($ulist == ‘5‘)) return;/$_REQUEST[‘filter’] = ‘5‘;/$similarities[‘ville‘] = ‘ville‘;/ (ville is a field created by Cimy user extra fields).
I’ve set up a page with the short code [userlist list=5].
The result is a list not filtered (for a non-admin user).
What am I doing wrong ?
Thanks for assistance.
