Hello everyone !
So I basically want to count the number of users who have 0 action, between 1 and 4, between 5 and 8 etc. over the weeks. My problem is I can't get those who have 0 action, I manage to have everything but this...
I don't really know what more I can say but I'd be glad to get some help even if it requires changing the whole query ! Thank you
