Formatting Titles...

[Marco Bagolin]

Hello all.
I must to format titles.

I write the following code:

\header {

dedication = \markup \override #'(font-name . "Book Antiqua") \bold {"Music from the Motion Picture"}

title = \markup \override #'(font-name . "Book Antiqua") \fontsize #+2 { \bold "TITLE"}

composer = \markup \override #'(font-name . "Book Antiqua") \bold  {"COMPOSER"}

arranger = \markup \override #'(font-name . "Book Antiqua") \italic  {"Arranged by MARCO BAGOLIN"}

tagline = ""

}

But what I wrote is not functioning correctly.
italic and bold commands are ignored.

any suggestion?

Thank you all for the help.

Regards
Marco B.
