Simple actionscript problem

[wreikun]

Hello everyone. I have a flash mx newbie question regarding some actionscript im trying to get working. I have an input textfield with an instance name of 'textfield1' and a button with an instance name of 'button1'. I want it so that whatever is in the textfield is passed to the php file in the server when the button is pressed.

Now, when I use the following actionscript, the value in the textfield does not seem to get passed to the php file cuz it comes up blank.

_root.button1.onRelease = function() {
var xxx=_root.textfield1;
var c = new LoadVars();
c.thisletter= xxx;
c.send("honban.php","_self","POST"
}

However, when I use the following different actionscript, the value I assign to 'c.thisletter' gets passed to my php file successfully and it works as expected.

_root.button1.onRelease = function() {
var c = new LoadVars();
c.thisletter= "A";
c.send("honban.php","_self","POST"
}

I would like to get the former actionscript to work.

Any help is appreciated. Thanks in advance,
REI
