I want to be able to capture answers to 'ranking' questions like, "Identify your top three choices of colour for the new office" and then have people place a preference on the ones they like. E.g. a completed answer sheet would be:

Options Rank

A. Red [ 3 ]
B. Blue [ ]
C. Yellow [ 1 ]
D. Green [ 2 ]
E. Orange [ ]

The variables are:

• The number of options available
• The rating 'direction' (1 is high or 1 is low)
• The number of choices that must be made (minium)
• The number of choices that can be made (maximum)
• A choice whether duplicate values are allowed (i.e. rate 2 twice)

Of course, your challenge is to make this easy to use on SMS. You could do this by just asking people to place their responses in order, i.e. the above would be "C D A".

Hope this is useful.
