Thanks.
First could not confirm this as a bug.
Worked fine on 2 Joomla 1.0 sites, except:
It can not work for plans which do not have subscription records (free lifetime plans with CBSubs setting to not also create subscription for free lifetime plans).
Tested both CBSubs 1.0.0 and 1.0.1, both are ok for plans with real subscriptions records in Joomla 1.0.
However then I tried on a third Joomla 1.5 site, and indeed the drop-down is empty.
So adding it to bugs for investigation. Thank you.
