Re: 6th special ending
so you mean that I should repeat measurenumber 17 - 23 after measure number 24 and call this special ending 1 and 2 and next repeat all the notes again and call this special ending 3 (with the other ending)?
This means a lot of notes duplicated. I put a new version on the next url
home.wanadoo.nl/pjvanderkroon/Jingle%20bells_02.nwc
Is this what you mean?
Not quite, see the attachment. I haven't checked all the bar numbers, but you didn't need to repeat quite so much...
And I uploaded the paper document of the notes (from which I entered the notes in NWC)

Another possibility would be to use a Dal Segno or perhaps a Da Capo for the 2 & 4 ending and a D(efault) ending for the 6th BUT, this will only look OK, it will not play back correctly because of how flow controls are managed in NWC.
To explain, NWC does not permit Master repeats to function after a DS or DC directive until a Coda commences, when master repeats function again.
