With a plain vanilla theme, I'd just paste in the single.php file, but I need help doing this correctly in Atahualpa.
Later: Never mind. I was pasting it in the correct field, but since all the text already in the field did not display, I was pasting my code in the middle of the existing code. So I copied the default code from under the field to a separate text editor, added my code, copied the whole thing, and then did a ^A^V in the field to replace what was already there.
