The offsite page link should be with http://www…
In your link there is no www… and in one link (theatre 1965-80) there is a folder theatre/(index.html not visible)
In the link to Theatre 1985-2012 there is no folder theatre and you link to a page called theatre.html#test.
The link in the offsite page must correspond exactly.
Perhaps http://www.actorclivefrancis.com/theatre/#test
or
http://www.actorclivefrancis.com/theatre/index.html#test
