Ringtone Help: Syncing/Installing

what are the correct settings I need to have checked off in Itunes 9? If I check off sync ringtones under the tabs it erases every freakin thing on the iphone!! grrrrrr

and I did have manage music/videos manually (which it unchecks) and it (itunes) won't let me drag/drop over to the iphone ringtones....

I am just really confused about the correct order of steps I need to get them over there without erasing everything EVERTIME I want to put a new one on there.

I did try dragging from my desktop to iphone ringtones which works, shows them there but only ONE shows up on my actual iphone under custom...

HELP!!

ok: I managed to get them on there....I had to uncheck manage manually and it put everything on my ipod (except for ringtones) then I was able to go back to the ringtone tab, and sync ringtones...but don't select just one, it erases the others!! so then I had to do it all over again....and select all the ringtones for it to be put on .... I think I am grasping how to do this but if anyone has the steps outlined better in what order I'd really appreciate it!!

Thanks so much!

 

Wow, I can't believe that not one person on this forum that has an iphone can help....or even TRY to help
