Music in my Ipod but playlists missing. Help please?

Question

When my ipod is connected to Itunes under  the "on this Ipod" menu it shows all my music.. However when i look for my playlists on the left side, the playlists do not appear. It's as though they've been deleted.All i see is the "recently added" folder. How does it go from being fine to all of a sudden no longer being able to edit my playlists that i've had for so long. When I go into the "On this Ipod" menu, i cannot edit anything..  I'm frustrated and really don't think i'd have to restore my ipod unneccesarily.........I keep getting emails from you telling me to hit SHift and S etc that does not bring back my playlists..Help! thank you! (i've attached some pics to better show you my dilemma)
Picture 1 shows the "On this ipod" menu         Picture 2 shows my music all there                    Picture 3 shows my playlists
Picture 4 shows my so-called playlists after i hit the DONE button and the "on this  ipod" menu disappears..

Answer 1

You have now started four discussions on this subject, two of which have been responded to.
In both responses, by different people, you were advised to turn on the sidebar in your iTunes Library. If that doesnot help you, please consider rresponding to one of the responses you have had. That way, you can enagage in discussion (converstaion) which might then give you the answer that you are looking for.
But constantly starting new discussisons isn't going to get you very far.
By the way, an easy (and perhaps easier) way to manage your Playlists is to manage them in iTunes, but without the iPod connected. Then, once you have finished modifying your iTunes Library (for now), connect the iPod and allow a Sync to put the modified Playlists onto your iPod.
