Questions Navigation Tree

Hi All

Does anyone know how to make the Navigation tree work when running a report?

I have grouped by projects and have them all appearing nicely in the tree, but when clicking on a project number in the tree, the report doesn't go to that group page. Is this something that should work, and if so, how does one get it to work?

Is there a trick to the group setup?

Thanks in advance for any help with this 🙂

Regards

Bev
