Thanks Jonathan — and for tidying it up, that’s much appreciated. The markup is terribly messy at the moment and that’s one of the reasons I’m revisiting it now as I know a little more now than I did when this was put together.
I didn’t include the radio button snippet as much of the code on the page will be changing over the coming weeks (I don’t envisage this causing a problem), but it will be going, with some other stuff, in place of the ‘details binding’ section that appears at present.
Thanks
