hey guys

i just signed up for wufoo - what seems to be a really awesome free online database service! i want to use it for a couple of simple things in my online christmas card this year

but have run into trouble hooking up their API. they have pretty good documentation for if you want to make your own custom html forms and hook them up to the database, but i want to communicate from flash (something i don't have a great deal of experience with on the PHP side of things) and am getting nowhere. would love it if someone could take a look at my code and let me know where i'm going wrong...

first of all the AS3:

Code:
    private function submitted(e:XmasEvent):void
    {
        var variables = new URLVariables();
        variables.Field1 = e.arg[0];
        variables.Field5 = e.arg[2];
        variables.Field3 = e.arg[1];
               
        var _request:URLRequest = new URLRequest("php/submit.php");
        _request.data = variables;
        trace(variables);
        _request.method = URLRequestMethod.POST;
             
        var _loader:URLLoader = new URLLoader()
        _loader.dataFormat = URLLoaderDataFormat.VARIABLES;
        _loader.addEventListener(Event.COMPLETE, sendComplete);
        _loader.addEventListener(IOErrorEvent.IO_ERROR, sendIOError);
        _loader.load(_request);
               
        _fillIn.removeEventListener(XmasEvent.SUBMIT_CLICK, submitted);
    }
           
    private function sendIOError(e:IOErrorEvent):void
    {
        trace("doh");
    }
           
    public function sendComplete (event:Event):void
    {
        trace(event.target.data);
    }
ok, here's the variables trace:
Field1=em&Field3=%0Dtest&Field5=20

(this is my wufoo form data from their site:
API ID Field Title
1 Name
5 Number
3 Message)

and here's my crazy trace from the sendComplete function:

eek! i can't read it! ok so onto the php:

Code:
    <?php

apologies for the long post. I have made the API key 000-000-000-000 but in my version am using my own correct key. anyone able to spot my error here??

thanks in advance
