What do I have to do to make a frame go back to the previous page?
If you mean you want to pull the music from e.g. page 2 back onto page 1, you can make a selection that spans what you want to be on the same page and make it into a frame. Or, add a frame break at the start of the first page, another frame break at the start of where you want the subsequent page to start, and activate the “Wait for next frame break” for the first frame break.
in the end what I wanted to do I have done with system jump because the option that you. It has given me it does not work for me I jumped to the next page too
