There are 2 visits and I want to get the percentage of patients who answered
either 1 or 4 for each question by each visit.

foe eg.:

question no.  visit  % of patients(who scored 1 or 4)

  1            1        25%

  1            2        35%

  2            1        26%

  2            2        37%
  .

  .

  20
Each of the patients has to answer all the 20 questions which will be scored
1,2,3, & 4. But I need to find the percentage of patients who scored either
1 or 4 only by question & visit.


Thanks,

jet.
