The unique visitor in Custom Variable

Hi all,

I’m using the custom variable feature in PIWIK. Everything looks fine except when it display on the dashboard the unique visitor number is not available.

The tracking code is

`_paq.push(["setCustomVariable",1,"clean_url",this.removeURLCampaigns(this.href.get()),"visit"])`

and dashboard

I’m also checking at http://demo.piwik.org and the unique visitor seems to be remove and display 0 in the detail view as well.

Is it possible to get a unique visitor?

Thank you very much.
