Sending variables

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

I am a novice actionscripter 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.

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. im not sure whether the code should go on the button. its really all going over my head. its also posted in Actionscript but I wanted to post here too. Hope thats ok?

Thanks in advance!
