Please help us help you and fill where relevant:
Your LimeSurvey version: [see right hand bottom of your LimeSurvey admin screen]5.2.9
Own server or LimeSurvey hosting:OWN

==================
[Write here your question/remark]
My survey has 11 Array questions. For each question participants can choose 1 of 5 options.

The question codes a Q1 - Q11 and the answer codes A1 - A5 with a different assessment value for each answer code.


I want to sum all the assessment values from all of the answers in a calculation in a hidden equation, but nothing I have tried worked.

How should I do this?

You have 11 question of type "array" with several subquestions?
Or one question with 11 subquestion as in your creenshot?

Nevertheless:
To access assessment values you use the property "QCode.valueNAOK"
[url] manual.limesurvey.org/ExpressionScript_-...#Access_to_variables [/url]

To sum the values you use the function "sum()"
[url] manual.limesurvey.org/ExpressionScript_-...mplemented_functions [/url]

And not to have to include each question and subquestion into this function you can use the ".that" variable
[url] manual.limesurvey.org/ExpressionScript_-....22that.22_variables [/url] 

This way it is only
{sum(that.Q1.valueNAOK,that.Q2.valueNAOK,,...)}

By the way: Why do you use these alphanumerical codes "A1", "A2", ... instead of numerical codes?
Now you will not be able to calculate later in your analysis any statistical value like mean, std. deviation or so, not be able to calculate statistical tests.

Please, read the linked sections of the manual,
Create a small test survey where you try out.
Create a test survey, with your tries, preferable in English, that you attach as lss.

See above{sum(...)}

I have made an example some time ago:
www.respondage.nl/scoring_an_array/

The page also has a downloadable file that explains (hopefully...)
