# My display rule for "returning customers" does not work

To test your "returning customer" display rule, please open your website browser (using refresh website button on your zotabox setting page).

Then close your browser and reopen again. (Please make sure your browser does not ‘remember’ your previous settings and re-opens your previously closed tabs – this will NOT trigger the ‘returning customer’ display rule).

You can also ‘refresh’ your website browser on the zotabox setting page to test again.

(This display rule will not work in private/incognito browser mode).
