[Plugin: DH Events Calendar] Works Fine !!

I tried to add some simple code to show which days have events, but it won’t accept the code, do you know why?

——–
$cadena = ‘var $highlights = [’04/30/2010′, ’05/01/2010′];’;

,beforeShowDay: highlightDays

public function highlightDays($highlights)
{
$cadena = ‘for (var i = 0; i < dates.length; i++) {‘;
$cadena = ‘if (new Date(dates[i]).toString() == date.toString()) {‘;
$cadena = ‘return [true, ‘highlight’]’;
}
return $cadena;
}
