I was referring to the fact that at the beginning there is a solo (Blank staff) that has 2 staffs in the treble clef and then there is a group of (Grand staff) and I didn't know how to make that Blank staff not to be a group to be Solo only in the treble clef without the bass clef.
I did a rehearsal "first and second end" and it works ok but when I do the second rehearsal I want it to jump from A. (point) to B. (point) which doesn't happen ... I only skip from B. (point) from measure 25 but I want the second time to skip directly from measure 24 to 27. Can this be done? If so please explain!
It looks to me like you want to start the endings after the first beat in 24 and 27. I would include the first beat notes under your first ending, and add them to the first measure of the 2nd repeat in 27. Then, follow Peter's instructions.
PS It really isn't necessary to use layers 3 and 4 in the bass clef. You can use 1 and 2.
I agree the D and F (24) should be included in the first ending but there isn't enough time for it to be added to measure 27. It will need to be rewritten some way. I think keeping the D and F in measure 24's repeat makes more sense musically.
One more point Cristi, it looks like you used ties as slurs. You do have some legitimate ties in your piece but you also have some slurs.
