Need more information.

Are you talking about how to assign instruments, working with the Score Manager, rearranging the order of the staves, or something else?

… or are you talking about Percussion Layout ?

Thanks to both of you for asking about the problem I was having. I was trying to figure out how to assign individual percussion instruments to certain spaces or lines in order to avoid having to try to make tiny adjustments with the mouse to get the correct note style and sound. A young lady at Make Music jumped in and told me how to get it done. Thanks again. Although I have used Finale for many years I have a lot of areas of the technical aspects that I haven't explored as yet. I am working on a little larger, more involved score so i may be facing more technical questions ahead. Again, thanks!

Glad your problem has been solved.
