Header surname problem

I may be dull and/or missing something, but I’m having trouble inserting either my full name or my surname into the header through the compile options. If I add <$surname> then the space on the header where it should appear is blank. If I add <$fullname>, then I just get my forename. If I put another tag, however - such as <$p>, then nothing at all appears. It’s baffling!

Anyone have any ideas please?

Just to clarify, is this in regards to the Mac version or the Windows version? I see your forum tag is set to Windows, but this is the Mac technical support section.
