Hi everyone,
I am new to LS and still trying to find my way around. This seems very challenging sometimes though!

I have three different questions (an MCQ, and two Array questions) in a group. I set an equation type question after each of the three questions to display the total score for each question.

I now need to get the total of all the three scores so I created a fourth equation question and did this :

{sum(q1Score, q2Score, q3Score)} but this gives nothing and keeps 0 all time

I then tried this:
{sum(!is_empty(q1Score), !is_empty(q2Score), !is_empty(q3Score))} but this gives the number 3 all times regardless of the three scores.

and finally tried this and got same as above:
{sum((q1Score), (q2Score), (q3Score))}

All the questions are on one page and my logic file is clean of any errors. No red highlights anywhere in my codes.

I searched the forums and manual for any info or examples to no luck !

I highly appreciate any help or hints to put me on the right way.

Thanks so much

LSS file?

Here is a shortened sample attached.

Thanks so much

I am not too overly surprised that you don't get any sums that make sense.

You are currently trying to sum up 3 strings and this of course won't work.

In your equation question you store "Q1 Score: →" in front of your value, which makes the whole thing a string and not a number.

I took out all the HTML and text and left only the sums that you calculate and this gives the correct values for scenario 1 and 3. Scenario 2 doesn't sum the values, but counts the questions that are not empty.

I'll upload the corrected question group here, just import it into your survey and you'll see the difference.

Fixed. I knew it must be something stupid I did.
Thanks holch, you taught me something that never occurred to me. Unfortunately like I'd said I'm learning only by trial and error in addition to whatever tips I find in the forums or elsewhere.

Many thanks
