Grace notes and Slurs

[Peter Chubb]

Hi,     
        How do I put a slur over a grace note or two?

I tried:

\score {
        \notes\relative c'' {
         a2 d,4*31/32 ( \tiny [e16*1/16 )d16*1/16]
        \normalsize cis8 d
        }
}

and got:
        x.ly:3:16: error: parse error:
         a2 d,4*31/32 (
                        \tiny [e16*1/16 )d16*1/16]

This is with lilypond 1.1.22.jcn2
