I am creating a survey that calculates the big 5 personality scores. It is basically a test with 80 questions divided in 5 areas, each with a different score. The questions are coded P001 to P080.

I have created a label set with the possible answer, identical to all questions: totally disagree, disagree, agree totally agree. The numerical values for the answer are 1, 2, 3, 4.

I need to calculate the 5 dimensions, so I have created 5 different equation questions.

One of the dimension contains the following formula:
{sum(P026,P052,P045,P069,P015,P072,P006,P066)}

The problem is that all the dimensions are 0, while they should contain the sum of the numerical values of the answers to the listed questions.

How do I achieve these calculations?

Many thanks,
Nicola.

Try this:

And ALWAYS add .NAOK at end of question code .

If one question his hidden : return false for all.
