Numbers and XML

[WilfCarter]

Okay here's the actionscript I am dealing with:

stop();
var NumChoice1 = undefined;
var NumChoice2 = undefined;
var NumChoice3 = undefined;
var NumChoice4 = undefined;
var TotalVotes = undefined;

	poll_xml = new XML();
	poll_xml.contentType = "text/xml";
	poll_xml.ignoreWhite = true;
	poll_xml.load('poll.xml');


function onResults() {
	NumChoice1 = poll_xml.firstChild.childNodes[0].firstChild.nodeValue.toString;
	NumChoice2 = poll_xml.firstChild.childNodes[1].firstChild.nodeValue;
	NumChoice3 = poll_xml.firstChild.childNodes[2].firstChild.nodeValue;
	NumChoice4 = poll_xml.firstChild.childNodes[3].firstChild.nodeValue;
	TotalVotes = NumChoice1 + NumChoice2 + NumChoice3 + NumChoice4;

	trace ("TotalVotes = " + TotalVotes);
	nextFrame();
}

And here's the xml I'm dealing with:

<Choices url="http://kungfudrew.com/poll.xml">
    <choice1>20</choice1>
    <choice2>2</choice2>
    <choice3>3</choice3>
    <choice4>4</choice4>    
</Choices> 

Now the trace TotalVotes will give me 20234 instead of 29. How can I convert these values (NumChoiceX) to numeric values?

You are actually joining strings together, use

TotalVotes = Number(NumChoice1) + Number(NumChoice2) + Number(NumChoice3) + Number(NumChoice4);
