Questionnaire (plugin)

Hello:

I am using the questionnaire to build self-assessments for different psychological constructs. The assessment questions usually fall into two or more categories.

Here is an example. Suppose I have 9 questions distributed in three categories and the questions for each category are non-contiguous.

Subtotal1 = A1 + A4 + A7
Subtotal2 = A2 + A5 + A8
Subtotal3 = A3 + A6 + A9

I would like to report the results immediately after the questionnaire is completed, along with some interpretive guidelines:

Subtotal1 = ##
The interpretive guidelines might be:
If [range], then [do this]
If [range], then [do something else]
If [range], then [do a different thing]

Then repeat for other subtotals / indicators.

Is this possible directly with the questionnaire module or do I need to build a back-end to handle this?

Thanks

Patrick
