I am creating a SharePoint "application" using custom lists for a customer to manage all its contracts with its employees who work at health care facilities. There are 20 facilities and one head office.
I have the following "Jobs" SharePoint list (the column "Emploi du siège", technical name is scECTREmploiSiege, is true for jobs that are only for the head office of the company):

So, there are 2 jobs for head office and 7 jobs for other health care facilities.
I have another SharePoint list for storing contracts in which the user needs to specify the facility ("Etablissement") and the job ("Emploi"):

As you can see on this capture, next to the "Etablissement" label there is a "count=7" label...
This label's Text property is set as follow:
Concatenate("count=";Text(CountRows(VAR_Emplois)))The OnSelect property of the Etablissement listbox I set the following formula (Emplois is the SharePoint list "Emplois" data source):
ClearCollect(VAR_Emplois;Filter(Emplois;scECTREmploiSiege=true))
So, whenever I choose a value in the Etablissement listbox, it should show me a label "count=2" because there are only 2 rows in the Emplois list for which Emploi du siège is true, but it does exactly the opposite : it selects the rows where Emploi du siège is false...
How is that even possible ? Any explanation ? What have I done wrong ?
Thank for your help
