Nextscene problem

Ok im doing a project for school and its got 5 scenes in it but
only the first scene moves on to the next wich is the 2nd and ive put the nextscene code after the frames in the 2nd scene but when i test the movie it doesnt move on to scene3 the scene code i used for all of them is

nextScene(); and i used it from the actions page can anyone tell me why after the second scene it wont move on?? do i need to put like nextScene(3);

or somthing like that? THNX IN ADVANCE
