Hi

I discovered I had a mixture of 2 problems: firstly there was a database integrity problem, and secondly my encoding of the qualifier over-enthusiastic (I hadn't realised that it's essential the url is only partially encoded, with the 'qualifier=' staying as '=' rather than '='.

Thanks for the pointers.

Liz
