Bedroom Screen problem

[KenJ]

Have a 2011 Sundance 2900MK. After removing the bedroom escape window screen, I cannot figure out how to reinstall it. The frame has no grooves snaps or clips to secure the screen. Not only that but the screen itself seems to be impossible to push back in place. Even if I could there is no way to secure it in place. This is the craziest thing I've ever seen! If any one has had this problem and solved it please post the solution.

Thanks for any help.
