 Hi John,
You don't need that set of curly braces, since you are already inside
the outer curly braces. You do, however, need to add brackets and a
comma operator in the inner return (the brackets get the precedence
correct for the comma operator):
for $bk in doc("book.xml")/book
return
<html>
<head>
<title>Hello World</title>
</head>
<body>
<h1>{data($bk/title)}</h1>
{
for $ch in $bk/chapter
return (
<h2>Chapter {$counter}. {data($ch/title)}</h2>,
for $sec in $ch/section
return $sec/title
)
}
</body>
</html>
