functions.php error – HELP!!

Hi all – I have updated a themes fucntions.php, and also the style.css and home-default.php by simply copying code and changing text size, I then enter the text I want to appear on the page via the themes options panel as required – but this new area does not appear.

What am I missing? The code is correct, I simply copy and rename a section of code called ‘header’ for example, and rename it to subheader, then use this same naming convention to update the css and other php it uses, but its not appearing.

Please help!

Cheers =)
