[phpesp-general] can't assign one group to more than one private survey

[Jobard <jo...@cy...>]

Hi All,

I have a problem with setting my surveys private with phpesp (latest 
stable version):
1. I have created several studies
2. All belong to different persons from the 'auto' group
3. Respondents groups have been defined

When I try to assign a group to a private survey, it works fine for the 
first survey. Then, the choice for that respondent group disappears from 
the dropdown choices when I want to assign groups to another study. 
Isn't it possible to assign the same group to two different studies ?
How can you do so ?
Help would be greatly appreciated !!

Thanks !

Gael.
