XML help, what is going on! :O

ok I have an XML

</Book>
<Book ISBN=“0743203178”>
<title>Nothing Like It In the World</title>
<author>Stephen E. Ambrose</author>
</Book>
</Books>

and a dynamic textfield called textbg which works fine

The trace below returns a value, but when I apply it to the dynamic textfield it does not! :open_mouth: why?

trace(xmlData.Book.(title==“Nothing Like It In the World”).author);
}

textbg.text=(xmlData.Book.(title==“Nothing Like It In the World”).author);
