Hi everyone, I’ve tried to implement a simple survey where a random number is generated, which is then used to assign participants to one of two groups. Participants then see different pages depending on the group they’ve been assigned. This is the survey: Pavlovia Survey The issue is that, while …

Hi Andrew, Honestly I’m not sure whether it will be fixed by next week. However, I’ve just written a workaround https://run.pavlovia.org/vespr/survey-group To launch a survey create a URL of the form https://run.pavlovia.org/vespr/survey-group?surveyID=733492ba-8997-416b-9c8c-4fe08c3519bc&group…

Hi Wake, I’m afraid when I click on https://run.pavlovia.org/Wake/survey-group I’m getting a 404 not found page

Sorry, wrong link. I moved it to https://run.pavlovia.org/vespr/survey-group/

[image] wakecarter: survey-group [PsychoPy] Thanks that appears to be working with quick test at survey-group [PsychoPy] Note for anyone else you then use Display page logic like {group} = ‘1’ I presume however this method will not pass Sona credit data to the survey - any chance of a vari…

What variable do you need to pass? It already passes participant.

Unless I’m misunderstanding the completion URL Sona is also expecting experiment_id and credit_token The completion URL on the overview page should look something like this: 'https://ucd-ie.sona-systems.com/webstudy_credit.aspx?experiment_id=453&credit_token=249cfe8d848b4e1bb0099f8386be61bc&survey…

Since experiment_id and credit_token don’t change for a given experiment then these can be hard coded in the overview page (as per your link). Is that working?

Hi everyone, Trying to go with random allocation of participants to groups and I have followed Wake’s workaround (thank you as always, Wake) but I can’t seem to get the pages to display according to that logic. I have put {group} = ‘1’ etc., in the logic for each page but it still shows all the pag…

Please could you show an example of a URL? You can replace some of the survey code with xxx if you want to keep it private. I also might need to update my code to cope with 2024 survey URLs.
