Your problem is that the period has a higher precedence than the comma.
Therefore it tries to end the variable definition at the period, overriding the
comma.

I don't like stringing a lot of variables on multiple lines like this - and this
is one of the reasons why (another is just style). Define them as:

var $root_category_id = 0;
var $max_level = 6;
var $data = array();
var $root_start_string = '';
var $root_end_string = '';
var $parent_start_string = '';
var $parent_end_string = '';

var $child_start_string = '<li%s>';
var $child_end_string = '</li>'."\n";

var $spacer_string = '';
var $spacer_multiplier = 1;

and your problem goes away.

You might also get by with:

$child_end_string = ('</li>'."\n"),

but I haven't tried it.

(P.S. Please don't top post).
