Hi folks, I am using Wake’s Post as a workaround to displaying 1 of 4 possible pages in a randomised way to participants. I have created 2 variables in the main survey logic tab under Calculated Values: randNum, which is set to random()*4+1 (so random number between 1 and 5) condition, which is …

I can’t see your expression question but I can see something called ranNum in the json code. How did you create it? I’ve just spotted randNum in your survey settings under logic, which may explain why it keeps changing. Try adding two expression questions on the first page, then make them invisible …

Hi Wake, Moved the setting of the expressions off the Logic → Calculated Values pane and into Expression questions on page 1. However, I still think I’m getting it re-evaluated on every click. it seems to randomise, but when I tick one of those questions on the page, it takes me back to the start …

Just a quick update on this Wake, it doesn’t seem like I’m taking the right approach to randomise people to conditions (pages). Wherever I have random() it re-executes that code on every interaction with the survey, which means they change conditions on every press. To fix this, is there a place I …

I’ll have to raise this as a bug. I’m sure it was working but not any more. Personally, I’m now randomising in PsychoPy and embedding surveys. However, the survey can’t yet read the randomisation so the effect of the randomisation has to either be a different survey (selected via nReps in a loop ar…

Thanks Wake. Is there a github issues page for Pavlovia Surveys?

I’m not sure. We use ClickUp within the team so I’ve created a bug report there based with my own demo of the issue: Pavlovia Survey I’m also noting (in a separate bug report but with the same demo as evidence) that you have to do something to random() to be able to use it.

Although this hasn’t been fixed yet, I’ve just written a workaround [image] Pavlovia survey issue with group allocation using a random number Pavlovia Surveys Hi Andrew, Honestly I’m not sure whether it will be fixed by next week. However, I’ve just written a workaround…

Hi Wake, im getting 404s when clicking these links, can you perhaps share your demo project so i can see under the hood? Cheers, Kris
