Thats not how remoting works. By sending an object to the server, the
gateway translates it into a or many structures that is in the argument
scope of CF.
to pass a string to a CFC do this:
public function sendToCFC():void{
var cfObj:Object = {input:source.text};
myFlashRemote.echoString(cfObj);
}
Now what this does is send an AS object through the gateway that will inturn
translate this into a structure with input as an argument with the value of
the send textfield's text.
Now, when you return something from the CFC, its best to bind that to a
Bindable variable.
In this case I would create a bindable var called returnString:String and in
my result function do this.
public function setReturnString(event:ResultEvent):void{
returnString = event.result as String;
}
To get to the result of your CFC call, a result function needs to be
specified or else the app will not know what to do with the result.
Here is your code changed to show how it all works.

Ok now I am starting to break down Clint's example so I understand
what is going on. I tossed out the AS just to kind of make me
understand how the tags are working together.
My question now is why cant I do this in my button click event:
myFlashRemote.echoString({send.text})"
Here is my current code and it works, but I want the text entered
into the TextInput tag to be passed to the remote object. Right now
I have static text in myFlashRemote.echoString()
