Problem strick!!!!

im panicking now with this problem.

The back button is appearing though out some of the pages and bigger than the size its meant to be showing. 

 The section Question page isn't working and not going in when going and wanting to go to that page, but when going into the adoption page, you see that page underneath it where its seen at the bottom only.

the back button showing again.

 cat section transition isn't going smoothly but a jolt with the question page again appearing.

Few night before its due, this happened. Been trying to fix it and looking though my codes and working out if Ive got extra divs or non-realvent things there but cannot find anything. starting again, adding things to it and taking things out of it. Each time it made it worse and functions changes and had to alter to make it work afterwards.
