AS2 Want to add text to ComboBox

I’m learning to build quizzes and tests dynamically in Flash CS3 using a combobox component to navigate between questions. Right now I have the combobox populate with the question number but I need it to say “Question” before the number (i.e., Question 1, Question 2, Question 3,…). Here is the code I have so far:

my_xml = new XML();
my_xml.ignoreWhite = true;
my_xml.onLoad = function ()
var info = this.firstChild.childNodes[2].childNodes;
for (var i=0; i<info.length; i++) {
ComboBox.addItem( {label:info*.childNodes[1].childNodes[0].nodeValue} );

If I put "Question "+ before {label:info… I get Question [objectObject] in my combobox.

How can I fix this?
