In Sheets how do I have a cell confirm a specific user has completed a specific activity as populated on a sheet from google forms?

Question

I have a google form that populates a row with answers including User and Activity. I have 75 users and 63 activities to check. On a second tab I have a column of users and a header row of activities. I would like this second tab to populate a cell green with "0" if it finds both the user and the activity on the form. I would like it top populate red with a "1" if it is not complete. This allows for a rapid check on what activities the user has completed and provide a way for me to also total up the number of activities remaining for any user or any activity as well.

The user is in column C on the form response and the activity is in column D.

=BYROW(TOCOL(A2:A,1), LAMBDA(u, 
   BYCOL(TOROW(B1:1,1), LAMBDA(a,
   --NOT(COUNTA(IFERROR(
     FILTER(form!C:C,(form!C:C=u)*(form!D:D=a)))))))))
