using UnityEngine;

using System;

using System.Collections;         // for using hash tables

using System.Security.Permissions;  // for getting the socket policy

using SmartFoxClientAPI;            // to setup SmartFox connection

All help is appreciated thanks to all who help in advanced

Your problem is code that doesn't belong to any function. The last lines of code (around "UnregisterSFSSceneCallbacks") are not within function scope so the compiler assumes you're trying to define a function without a return type.

Clean your code. I guess what you want to do is to remove that code entirely. It seems to belong to the partially commented "void OnRoomList(Hashtable roomList)".

Stripping away the comments and improving indentation yields the following code.

Can you see now where the error is?

    public void OnLogin(bool success, string name, string error) 
    {
        if ( success ) 
        {
            statusMessage = "Login for user \"" + name +  "\" successful.";
        } 
        else 
        {
            statusMessage = "Login error: " + error;
        }
    }

    // Tons of comments removed...

            UnregisterSFSSceneCallbacks();
            Application.LoadLevel("sc_City");
        }

        catch (Exception e) 
        {
            Debug.Log("Room list error: "+e.Message+" "+e.StackTrace);
        }
    }
}
