Hi
I'm trying the get my survey to calculate and save to the db subscale scores and totals.
I can get expressions manager to add the answer values from an array (5 point choice) question, eg:
This will show and save the answer to the db. the question type where the expression is entered is equation

But when the question type is a general array and the answer values are numeric (1,2,3..) the same expression won't calculate. I don't see a way to force the question to be considered as 'numbers only'.
I need a general array as the answers are categories with text descriptions (not just numbers, or yes/no..)

So... how do I do expressions maths on the array (general type) questions?

thanks!

OK i think i just found my answer. when the array's answer option codes are numeric (1,2,3..) then use:
{sum(question1_SQ001.code, question1_SQ002.code)}

.. yes?

Yes, and furthermore you can use the "that" variable.

{sum(that.question1.NAOK)}

I don't understand why you can not use the assessment values and qCode.value in a normal array. If I assign assessment values, this works for me:




Sample survey attached:

thanks for the replies - problem solved. LS is so feature rich I just don't understand all the options yet (ie assessments get me very confused).

cheers
