Q:

Make section font all caps

I am using the following code with sectsty to make all sections use small caps:
\sectionfont{\sc}

However, I want them all typesetted in lowercase, but the following does not work:
\sectionfont{\MakeLowercase\sc}

A:

Since \MakeLowercase takes an argument, try flipping around your macros:
\sectionfont{\sc\MakeLowercase}

You should also use \scshape instead of \sc.
