Signalr error on namechange

So I just started off trying to work with Signalr for a project I'm working on. I have fairly little experience with JScript or Jquery, but a decent amount of experience with C#

I made the tutorial project on microsoft docs for a chat app [over here][1].

So this is probably a fairly dumb question in the eyes of most.

in the script I replaced

chat.server.Send($('#displayname').val(), $('#message').val());
with

chat.server.GetServerName($('#displayname').val(), $('#message').val());

and in the hub added the function

public void GetServerName(string name, string message)
{
// Call the broadcastMessage method to update clients.
Clients.All.broadcastMessage(name, message);
}

But I'm getting the following error.

> Uncaught TypeError: chat.server.GetServerName is not a function

If all the rest of the project is identical, how does this happen?

My apologies if this is a duplicate, I've been looking for almost 5 hours with no sensible answer to my question elsewhere that I'm aware of.

Normally you need to start the method name in lowercase when calling from SignalR client

chat.server.getServerName($('#displayname').val(), $('#message').val());


Replace **GetServerName** with **getServerName**

Use invoke method of the Hub to call server methods from the client:

yourHub.Invoke("GetServerName", $('#displayname').val(), $('#message').val());
