Thank you very much "Theducks" & all the people that have helped. I managed to load my entire library on to my kindle by adopting your advice and configuring my device icon by basically copying your kobo template:
MyBooks/{series}/{series_index:0>2s||-}{title}-{authors}
I don't know why my kindle needed configuired as it had been working well for two years before.
Now I just need to stop the kindle displaying the authors as first name first. It appears as surname first on calibre.
Again many thanks, it's greatly appreciated. BFJ
