I have a problem with the “Complete” button using pavlovia surveys. I want to change all the buttons text to spanish, which I do editing the JSON, however this only works for the back and next button, while the complete button still says “Complete” although I have changed it in the JSON.
I encountered this exact problem as well. I tried manually changing “completeText” to “pageCompleteText” and “pageCompText”, so it’s more like the pagePrevText option, but those also don’t work.
The problem does not appear when I’m previewing the survey in the browser from the dashboard. But once downloaded and embedded in the experiment, the text does not change anymore.
