two-sided problem

[胡海鹏 - Hu Haipeng]

Hello,
  I'm trying two sided printing. It's strange: I set inner 40\mm and outer 10. The odd pages are ok, but on even pages, the score is shifted very left, and the instr names are eaten. In my opinion, the even pages must have left margin 10 and right 40 for binding, but the right is too wide and the left is too narrow. When I set inner to 30 and outer 23, the odd pages are not so good. Why? NR says inner/outer margins will override l/r margins. Must I comment out these margins I used to produce single sided version?
