Hi!
I'm getting lost with the attempt to calculate a score based on a multiple question to screen out respondents. I researched a lot in the forum , but couldn't replicate what I found. I understand that I need to calculate a score with the help of an equation question and with another equation setting a certain value to a list question to be able to set a quota.

Say I want ask people what sports they are doing (Multiple choice) and only continuing the survey with those who do certain sports.
1. Therefore I assigned a code value of say 100 to "Jogging" and 50 to "Skiing"
2. Now: if I want the Survey to be continued with Joggers only I manage to get with an equation a score of 100 by the following {if(Q1_100,100,0)}, however I'm not able to write the right expression that calculates the sum of all codes that are checked in Q1? How would I do this?
3. To screen out all that are non-Joggers or non-skier I tried as I found in the forum with the forum with another equation: {Q2=if(SQ1 > 49, "1", "2")} but this doesn't set the values in Q2 as I thought it should.
Any idea what's wrong? See attached the short .lss file
Thanks!

1. & 2. You can compute Q1 score in an intermediate equation type question (Qscore) using something like:
3. Use as Q2 question text:
BTW you can do the same more directly avoiding additional Qscore equation:

This is brilliant. Thank you.
The only stuggle left: To screen out I would have in Q2 code 1 or 2 be set as "Yes", so I could set a 0 quota.
However, if I follow your recommendation I get in Q2 as question text 1 or 2, but obviously that won't help me to screen out.
What am I missing?
Thanks so much!

For this I don't use quotas but just a conditional javascript redirection, pasted in the source of the next group group's description (check survey settings if group description visibility is on)

Thanks Benoit. This is clearly the advanced mode (and I'm not entirely sure I'll get it done this way).

Nevertheless as a matter of interest:
My equation question is with your help defined to give me either a 1 or a 2 as a result - so far so clear.
How can I then make sure that my subsequent question has a default value automatically either code 1 or code 2 checked depending on the result of my equation question.
My thinking was that by doing so I could use also the quota function in the survey settings to screen out to keep better overview.
So the logic must be somehting like if SQ1=1, Q2_1 = Y, but this seems to not work.
Thanks again for your support

I'm not a quota expert but as far as i know you can't set quota based on an equation question... that's why I simply use javascript. Note that it's ok because screen out are just quota with "0" value; It's not possible to use this trick for "real" quotas with value > 0 (and have to apply some count)

You can easily enhance/adapt the provided js code to fit your needs.. For example:

In fact : you can set a quota with Equation :
Use 2 question : one "single choice" + one equation.

The quota is done with single choice question
Equation :
QUOTA={if ( ( qCondition == 1) || ( qCondition == 2) ),"OUT","OK")}
