I have the same issues. Giving two conditions in the choice filter column.
What I actually want is that I have a list of staff. I want to filter the staff list based on a specific location and a specific project selected above the form. i.e. assume if I select location A and project B, all the staff of location A and project B should be displayed. and if I change my selection to location A but project C, only the staff list of location A but project C to be displayed.
Waiting for your soonest reply.
