I would like to be able to count how many options a multiple-choice question is marked and use them in a relevant group equation.

For example:

Q1 (multiple-choice question)

Opt1 --- X
Opt2 --- X
Opt3

In the example the question Q1 has marked the response options Opt1 and OPT2 and relevant equation for a group of questions I would like to do is:

If Q1 has more than one option checked and Opt1 == "Y" the group is shown.

Thank you very much.

Try:

Thank you very much for your quick response.

Now I would like to assign a value to a radio list type response. That is, the value will be marked in the question depending on the relevant equation.

For example, the radio-list-type question is Q2

And the response options are:

V1
V2
V3
V4

Following with the previous example:

If count (that.Q1)> 1 && Q1_Opt1 == 'Y' then Q2 = V2
If count (that.Q1)> 1 && Q1_Opt2 == 'Y' then Q2 = V3

How can I write that?

And also, where do I have to put that code? In the relevant equation of the question?

Thank you very much

Please refer to the manual - manual.limesurvey.org/Expression_Manager..._Assignment_Operator

So, in you case, the assignment equation would be:
That would be placed in a hidden (via CSS) equation type question directly following Q2.

Just, to add:
Why did you start a new thread for this last question?

Now Denis and I answered it in the other thread, Tony here.

So it's confusing.
