I'm collecting data for my Pavlovia survey via Prolific and half the data isn't being saved!

Hi,

I’ve created a survey on Pavlovia and I’m using Prolific to collect data. I’ve got 50 completed participants on Prolific but I only have data for 26 participants on Pavlovia. I’ve tried everything I can think of to ensure that this doesn’t happen (having looked at previous forum posts), like using the URL parameters so it records the prolific ID instantly, using the completion URL rather than providing a completion code, and nothing seems to be working. It just seems to only be saving half the data.

Please help!!

Hi,

Sorry I don’t know what you mean by “a code component”. I’m just working in Pavlovia, no PsychoPy.

So is the Prolific return URL here:

Do you have anything in your survey here:

No problem.

Yes, the completion URL from Prolific has been copy and pasted into the completion url on the overview page in my survey.

I also have the same completion URL in the ‘redirect to an external link after submission’ box.

Try removing it from the second location.

Dynamic Survey Completion URLs Do not use the Dynamic URL in the Survey Complete section of the survey properties. This is not compatible with Pavlovia Surveys [image] Instead you should use the Experiment Flow section of the overview page.
