Hi, I'm trying to prefill a single choice question based on a numeric response. See below.


Q2. How old are you? (Numeric)

Q2Equation: {Q2Quota=if(Q2<=39 AND Q2>=18, 1, if(Q2<=49 AND Q2>=40, 2, if(Q2<=99 AND Q2>=50, 3, "")))}

Q2Quota: Contains the 3 bracket ranges with answer codes 1, 2 and 3. This is on a new page.


When testing, Q2Equation shows the correct result but doesn't insert it into Q2Quota, but there is no syntax error displayed.



If I change Q2Quota to a multiple choice and update Q2Equation to:

{Q2Quota_1=if(Q2<=39 AND Q2>=18, "Y", "")}
{Q2Quota_2=if(Q2<=49 AND Q2>=40, "Y", "")}
{Q2Quota_3=if(Q2<=99 AND Q2>=50, "Y", "")}

Then it works, and is prefilling correctly.


Am I doing something wrong here, to prefill into a single choice?

Hmm...it works for me but I find it odd that I have different syntax highlight colours in the equation question.



Sample survey attached:

Thanks for the reply tpartner, it works for me. The syntax highlighting seems different based on question order, and this affects if it works or not for me.

See table:



It seems odd that multi works and single choice doesn't with same order :blink:

Blue color : same page
Bold pink : a page after

For equation set (use QCODE="value") remin it's set only in PHP and when validate the equation question (at the equation question step).
