Need help with a formula field -- Trying to populate a new field based upon whether or not the original fields are blank or not.

Thanks for your help.  This is not quite working the way I had intended.  When I tried the above it is grouping in the filter as:

Question 1 Taken

Question 1 Taken
Question 2 Taken

Blank

What I really want is just:

Question 1 Taken

Question 2 Taken

If there are blanks they should be excluded.  When I refer to the filters they are the dynamic ones on the report, not within the report criteria.  I don't want it to be grouped into a new filter option if the user answers both questions.  The use case is tricky and perhaps it would be easier for me to send a screen shot and full use case?  Unless the above makes sense and is something simple I am missing. Thanks again.
