[Help] With <List>

[wutang001]

Hi
to briefly explain what I'm trying to do, is the following:
1 user creates a group, and the 2nd joins the specified group.

My problem is that the Count is off, I'm doing something wrong obviously. Here is some code snippits
So this is the actual function.

public class Groups
    {
        public User _User{ get; set; }
        public List<User> Users { get; set; }

       public Group(User user) {
			_User = user;
                        Users = new List<User>();
		}

So this is where it gets used

Group group = new Group(user)
case 1: //Create Group
group.Users.Add(user);
int eg = party.mUsers.Count();
Console.WriteLine("Users" + eg);
                    break;
                case 2: //Join Group
                    group.Users.Add(user);
                    int eg = party.mUsers.Count();
Console.WriteLine("Users" + eg);
                    break;

To explain a bit more, I have a Client - Server connection and there is two clients connected to the server. Case 1 is "user 1" (client 1) creating a group, and Case 2 is "user 2" (client 2) joining the group. Now, the problem is that the count is always 0. Why is this? how do I fix this?
Thanks.
