Thanks again Denis
The problem is that this survey is anonymous because it contains personal information (age, gender etc.) I would prefer if there isn't a direct link to their answers, but instead the results they receive at the end page (I know the title of this thread can be a bit confusing...) The PDF file that PDFreport creates contains this information, but is separate from the survey. Also, in this situation it is easier for the users to write down a number (e.g. fu_321476458644) than a link to the survey.
My idea, that involves your PDFreport plugin, might be worse than reloadAnyResponse, but it would solve my problem. There are other situations where I would prefer reloadAnyResponse, but not here.
Is it very difficult or completely impossible to do what I suggested? Further explanation or suggestions are welcome.
