You can easily add a pre-check to avoid runtime errors:

   repeat with i=5 to 12
      get item i of enil
      if it is not a number then -- 'not an integer' if more appropriate
         answer error "Not a number:" && it
        add it to tLesVars["total"&i]
      end if
   end repeat

The error msg may include the problem line number and item number, of course.
