The second param to NetConnection.call is not a function but a reference to a flash.net.Responder instance (or subclass). Try this instead:
import flash.net.Responder; private function SendUserMessage():void { ChatServer_nc.call("SendUserMessage", new Responder(SendMessageResponder), AccountLoginResults[0].USERNAME, UserMessage.text); } private function SendMessageResponder() { } Using a Responder allows you to optionally specify a fault handler as well.

Searching the net for an example of the Responder has not resulted me in any results which I can understand. In my MXML file I have a button which calls a function of SendUserMessage which is listed below: private function SendUserMessage():void { // Send what the user has said to the Remote Shared Object so everyone can see the results ChatServer_nc.call("SendUserMessage", SendMessageResponder, AccountLoginResults[0].USERNAME, UserMessage.text); } private function SendMessageResponder() { } Now In FB I am getting an error message which says Implicit coercion of a value of type Function to an unrealted type flash.net:Responder. Does anyone have an example of sending what as user has typed into a text box to FCS/FMS and then having that being displayed within a textbox.
