you could try something like this:
IF REGEXP_MATCH(UPPER([User Category]), '^[A-Z].+') THEN [User Category] END
Thanks Peter, unfortunately REGEXP is not available to me on this DB
So I was able to get this to work by using the same calculation except I removed the *** and just used a space.
I probably should have tried this before posting...
CONTAINS([User Category], " ")=true
