When I sync my iphone with itunes why do my playlists not copy over?

I created new playlists in itunes, but when I sync my iphone, the playlists do not show up on my iphone music. What can I do to get them to copy over?

Try turning itunes match off in itunes on your computer & then turn back on. After this completes go to view, view options & make sure check marks are next to cloud boxes. After this is completed and everything shows matched or uploaded.turn off itunes matc on your phone & wait for everything to clear out.turn match back on phone & see what happens
