Dear all
I've been looking into the server database (through PHPPGADMIN, a client). In this database, numbers are all positive.

Have I looked in the right place? another possible place (more "in the roots")?

I think the LS system has changed the negative into positive (because I have a great amount of answers, I think all the filled answers).

The problem is that a week before the survey laucnh, I operated an upgrade to solve a problem with "no-yes" question (2.50+ 160416). Then with the new version I had problems with the model (the model I created based on the default was not working anymore). So I focus on this issue, and I haven't test ALL the data export again (the cursor was working on the previous version, before 160416).

Anyway, I should have looked carefully to the export, but the fact that bugs are different from one version to another is quite tricky for non expert. I know... this is the idea of free development softwares.

I don't know what I will do now with my problem. Seems bad...

Thank you for you help !!!
