Parent folder FAQ's count are getting displayed and Sub folder FAQ's count are getting displayed. But I need Parent Folder FAQ's count to be sum of FAQ's of Sub Folder of respective Parent Folder.

Eg. Parent Folder(2) > Sub Folder(2) > Sub Sub Folder(1)

But I need output to be displayed as below

Parent Folder(5) > Sub Folder(3) > Sub Sub Folder(1)
