Change scene doesn't work...

Dar

Ok so I have a scene where you can choose what level you want to play. And on it there are 12 buttons: Level 1, 2, 3, 4, 5, 6, 7, 8, 9,10, 11 and 'back to menu' button. On each of them I have set so when they are clicked the scene changes (using change scene) to the scene I want; however, let's say I want to go to level 3, but when I click on it it takes me to level 5. So then I try level 6 and again it goes to level, and it's the same for every level! They all go to level 5. And when I check, they are set to their proper level but they just don't do it...

Is there a problem with change scene for you guys too? or is it just my mac?
