Assuming the question is mandatory and given something like the following:
- Question code: Q1
- Y-scale codes: Y001, Y002, Y003
- X-scale codes: X001, X002, X003...
You could insert something like this for the "Question validation equation":
- Question code: Q1
- Y-scale codes: Y001, Y002, Y003
- X-scale codes: X001, X002, X003...
You could insert something like this for the "Question validation equation":
Q4_Y001_X001 > Q4_Y001_X002
AND
Q4_Y001_X002 > Q4_Y001_X003
AND
Q4_Y002_X001 > Q4_Y002_X002
AND
Q4_Y002_X002 > Q4_Y002_X003
AND
Q4_Y003_X001 > Q4_Y003_X002
AND
Q4_Y003_X002 > Q4_Y003_X003
AND
