Token in email links is not populating values

Hi,

I have a nurture campaign with some emails and I add some URL parameters in each link in the emails. I'm using tokes so it's easier.

The link in my email looks like

http://www.presidion.com/analytics-resources/what-is-predictive-analytics/{{my.url_track}}

And the tokens are nested like:

{{my.url_track}} = ?utm_source={{my.utm_source}}&utm_medium={{my.utm_medium}}&utm_campaign={{my.utm_campaign}}

{{my.utm_campaign}} = General_PA_Nurture_Track

I think it was working last time I tested it, but now that I'm running the final test before launching the campaign this is what I get when I click in the link

http://www.presidion.com/analytics-resources/what-is-predictive-analytics/?utm_source={{my.utm_source}}&utm_medium={{my.…

Does anybody know how to make it work? Is it because of the nested tokens?

Thank you.

Irene
