Thanks, this is great! It's not a case of it being poorly written (far
from it), more like 'well concealed'. :-)
I can't find links to this from anywhere on your site, and the search
feature doesn't find it either.

Mind you, if it's a chapter from your book that you quite rightly
charge for, it's no wonder you're not waving it about for free. Or
should I say, you weren't...

Reminded me again of how I really need to borrow someone's credit card
sometime soon. PayPal doesn't like debit cards - even ones that the
bank sends you a whole tree's worth of (snailmail) spam about, making
claims about how universally accepted they are :-(

Took me long enough to get there though :-(
