Many thanks to all of you here for your help.
@aakk9999 for the solution, @g1smd for the fine tuning suggestions -- I implemented them, @phranque for educational encouragement (I'll get around to it someday, really I will!), @not2easy for confirming gremlins in the details of WP, @Panthro for injecting some humour when I needed it most, and @lucy24 -- just because -- how could we live without you?!
