[FX.php List] follow-up to Sort within a found set

[biscuit technologies (gmail)]

Hello again,
I've reloaded the example file and db and I'm still getting errors, so  
the basic file set doesn't seem to be working.

Can anyone confirm this?

On the BookList files, I can do a search successfully, but when I  
click on a column header to sort I get no records found and an  
Undefined variable error for line 55 which is

         $currentSearch .= '&' . "$key=" . urlencode($value);

Thanks,
David
