Please upload your capx so we can see the problem.
Few things I can think of -
Your using the same event sheet for level 2 so it's telling you to go to the layout your all ready on.
Or you have not assigned the collision detection on the level2 event sheet.
If none of the above are the issues then a quick solution is to clone the door, name level2door ect then test for the collision on each layout with the appropriate door.
As for the menu. Make sure you have a menu event sheet
