header.php ‘title’ help please

Morning all,

I am using author.php to generate profiles, here’s mine: https://www.elyonline.co.uk/archives/author/kb/

but I need to have the browser header say ‘Ely Online’s Karl Bedingfield’, currently when you go to that page it says: ‘Ely Online Archives’.

Is there a way to do this? This is my current dynamic title code: https://phpfi.com/65855

Any suggestions?

Thanks
Karl
