Look more closely:  you have extra "$" on the above two lines.

} (function else)               basename=${$convertspaces:h} 
} (function else)               cd '/Volumes/'$basename
} (function else)       fi
} (function)   }

I've pointed out the reason for the error message, but I don't vouch for
the correctness of the function otherwise (see Mikael's mail).
