Dear all,
I'm builing an app which should show if my drivers have made their daily report or not. A kind of pivot table, in other words.
The data to be analyzed comes from a sharepoint list, with driver ID, date, and information about the daily work.
The screen to display the reports yes/no looks like this:

I wanted to create a table or gallery for each driver in the row and each date in columns with yes/no or 1/0 or whatever to visualize the result. I tried with countrows after filtering my sharepoint list, but it seems that "double" ForAll is not possible?
Thanks a lot for your ideas or suggestions.
best regards
Paul
