I've now compiled everything into iWeb and everything is working. I did have a few problems saving iWeb files and opening them again which resulted in me having to redo a lot of work. But now I have it all working I'm pleased with the result. I would really have liked to extend the narrative further and include more animation but I ended up not having time. I think my original plans were a bit ambitious so I had to change things a little but I am still happy with the result.
