IPHONE 3gs and Note Pad App

Downloaded this yesterday and it now appears in my Apps in both the phone and list of Apps in Itunes.But I am stuck on why the data I have written in the APP doesn't appear on the PC, after several syncs. Under sync notes, it sits on "Add Computer" and instructs me to open the sync app and then loading a passcode to the device.There seems to be no obvious way to open "sync" on the PC.As always, Itunes shows the Iphone is connected and there are no other issues with other apps.
I have asked Apple discussion groups but no answer is forthcoming.
Thanks
