I would like to confirm that I have this nested-if written correctly. I have traced it through the debugger and it goes from line 9 to 15 to 22. I have used the debugger to verify that the value for "cohort category" is "Cohort 1" and "test retest subset" is "Yes" before step 9. I can't figure out why the if statements are returning false. Are my if statements syntactically correct?
