Rotation is not working properly?

Question

Hi I am trying to present in a random order a pair of pages. All work fine except that at the end of the questionnaire for some reason some pages with the questions answered are presented again. Cannot find the reason why.
I am copying and pasting the code from the
random generator and the general structure of the questionnaire.

Answer 1

In this line ...

setPageOrder($pages,'Τέλος'); 

... you tell the questionnaire where to resume after the last page of the rotation. This is a page with the ID "Τέλος". However, I cannot find a page with that ID in your questionnaire. Actually a warning shall appear that the page cannot be found. However, it may be that SoSci Survey removes any non-ASCII-characters in the ID (which leaves an empty string), because page IDs must only contain ASCII chars, and then sees that no more page was specified (also it would be required).

Thank you so very much. I actually realized that and corrected it before I received your response. Thanks for your excellent tool and the quick responding!!
