Hello Imacklin,

well first at all, please do not use pics to show your CODE!
It is better for all to have the CODE inside a “CODE-TAG”, which you will find here…


I am not sure, but i think you have a failure in your “onReady”-code part.
You do GET before you SET!

First SET —> then ----> GET !

$w.onReady(function(){
   session.setItem("page", wixLocation.url);
   previousPageURL = session.getItem("page");
});

I think this will cause the error in your code.
