Yes that's the correct page.
Yes sorry I meant quarter notes
I wondered if that was the case about a missing half note, or the Bb being a half note, so I tried to find other copies of the score, which all presented it in the same way. What you have said makes sense though, because the music matches your description and not what I see on the page.
Thanks for the help rainer, it's very much appreciated (and tells me how the melody should interact with the accompaniment)
I wonder why they are so many copies that don't show which are sixteenth and which sextuplets though :S
