Trouble Sending HTML Form Data

Question

I've been tasked with replicating the following HTML in actionscript for the integration of a flash frontend onto an existing cart system:
HTML Code:
<form name="campaign" method="post" action="https://www.client.net/portal/site/client/template.APPFORM?app=CL_OC">
<input type="hidden" name="campaignSnippet" id="campaignSnippet" value="<campaign trackingCode="testing" xmlns="campaign"><ATONCE><styleColor number="123456-789"/></ATONCE></campaign>"/>
</form>
Now, I've been able to build the value string without any issues, but getting it to post successfully to the server is what's giving me problems. I've been able to use the above code in an HTML page to post the item to the cart successfully, but my code in AS3 (below) isn't successful:
ActionScript Code:
var sendOrder:URLRequest = new URLRequest( "https://www.client.net/portal/site/client/template.APPFORM?app=CL_OC" );
sendOrder.method = URLRequestMethod.POST;
var variables:URLVariables = new URLVariables();
variables.type = "hidden";
variables.name = "campaignSnippet";
variables.id = "campaignSnippet";
variables.value = encodeURIComponent(stringBuilder);
sendOrder.data = variables;
sendToURL(sendOrder);
(stringBuilder is the value string from the HTML snippet above)
What am I doing wrong in building the HTTP request?
Thanks in advance for any help you can throw my way!

Try:
var sendOrder:URLRequest = new URLRequest( "https://www.client.net/portal/site/client/template.APPFORM?app=CL_OC" );
sendOrder.method = URLRequestMethod.POST;
var variables:URLVariables = new URLVariables();
variables.type = "hidden";
variables.name = "campaignSnippet";
variables.id = "campaignSnippet";
variables.value = encodeURIComponent(stringBuilder);
sendOrder.data = variables;
var loader:URLLoader = new URLLoader();
// loader.addEventListener(Event.COMPLETE, finished);  // optional
loader.load(sendOrder);
