Dear all,
I'm having some issues creating a question validation equation. I've created an array question with six sub-questions and two possible answers (yes, no). Participants need to answer "yes" to the first five sub-questions to move to the next group, and the answer to the sixth one is up to them. I've created the following validation equation, but it is not working.

(SQ001 == AO01) and (SQ002 == AO01) and (SQ003 == AO01) and (SQ004 == AO01) and (SQ005 == AO01)

I have no previous knowledge about coding, so I would be very grateful for any help you can give me. I have uploaded a screenshot of the question, whose code is G07Q39.

Thank you all in advance,

Christian

(SQ001.NAOK == "AO01") and (SQ002.NAOK == "AO01") and (SQ003.NAOK == "AO01") and (SQ004.NAOK == "AO01") and (SQ005.NAOK == "AO01")

1. Usage of NAOK : manual.limesurvey.org/Expression_Manager#Usage_of_NAOK
2. Variable : manual.limesurvey.org/Expression_Manager#Access_to_Variables (here AO01 is not a variable, it's a value).

And to add:
[url] manual.limesurvey.org/ExpressionScript_-...code_variable_naming [/url]

1. The answer option code "AO01" is a text, not a number; therefore it has to be surrounded by quotes.
2. As you read in the link above, a variable is accessed either by

• "single punch question: "QCode"
• "multiple questions, arrays, multiple text, multiple numeric": "QCode_SubquestionCode"
• "array(text), array(number): "QCode_SubquestionCodeYAxis_SubquestionCodeXAxis"
• "dual array": "QCode_SubquestionCode_ScaleID"

Dear all,

It works perfectly now! Thank you both so much for your help! I've learnt a lot today  .
Best wishes,

Christian

By the way:
you can validate this more easily by:
countif("AO02",self)==0
or
countif("AO01",self)==5
or (if you use numeric codes (1,2) instead of ythe dehault "AO01",...
sum(self)<6

Read the manual about implemented functions 
[url] manual.limesurvey.org/ExpressionScript_-...mplemented_functions [/url]

and
[url] manual.limesurvey.org/ExpressionScript_-....22that.22_variables [/url]

And:
Why do you display this question instead of the private policy option?
