You need to use the State to store the intermediate values that you will need in any of the parent or child dialogs. In version 4 you can do that using the BotAccessors something on below lines

 public static string CounterStateName { get; } = $"{nameof(BotAccessors)}.CounterState";

    /// 

    /// Gets or sets the  for CounterState.
    /// 
    /// 
    /// The accessor stores the turn count for the conversation.
    /// 
    public IStatePropertyAccessor CounterState { get; set; }
