Hi Mary,
True 
- and good point about the manipulation code. I need to update my themes at some point, they weren't broken for me so I did not fix them. But it just goes to show that the obvious is not always visible. That when you are too close to something then you can find it hard to see the whole picture. Software solutions do evolve over time as more knowledge and understanding is gained. That's life!
Cheers,
Gareth
