Flash form sending variables

OK. Im in at the deep end guys & I need your help.

I am a novice flasher and i know my limits but I am building a site at work at the moment & just found out I have to integrate a registration form (actually, two registration forms, one for students one for teachers) into it.

Rather than using the php tutorial on here, I have to take whats entered into the fields & send them to eloqua which is the system they use for database & tracking emails etc.

The info I got from eloqua is

//SEND DATA - Take usual flash form and pass Eloqua hidden fields and flash fields using Eloqua form information ==============================
var sendData = function(){
var EloquaVars = new LoadVars();

EloquaVars.elqFormName = 'Axios_Form_Name_Here';
EloquaVars.elqSiteID = 'Axios_Site_ID_Here';
EloquaVars.defaultTargetURL = '';
EloquaVars.elqPost = '';

EloquaVars.eloquaFieldName = flashName.text;

EloquaVars.sendAndLoad("http://now.eloqua.com/f.asp", EloquaVars, "POST");
gotoAndStop("End");

}

And now Im not sure what to do. Can anyone help? i would very very much appreciate it!

I have attached the fla file in case someone can help. Thanks in advance!
