So sorry for this, I had read and understood that it was the button menu where Auto route was located but have now seen a video tutorial which explained where it was and also I was trying the Next button after using Multi chapter index and I now understand that you cannot see this in Preview, it is neccessary to build the project and try it, so as the flowchart was looking good I can only presume , and later will try, that it will work OK.
Thanks for your comments though , much appreciated.
