Error: Cannot modify header information – how can I edit my functions.php?

This is the full content of my functions.php (It has default theme stuff in it even though the theme files are coded from scratch. I just used the default for the parts I don’t want to rewrite)

Never mind, I went back to the drawing board, found the “list subpages” plug-in and swapped in the Andreas code instead of the code it came with. Basically I took the long way around to do something that I probably could have done in 5 minutes.
