Thread: Calling Polymorphic Function

I am getting an error compiling the following code.
Beverage is a private member of type pointer to BeerScore.
I create a new AleScore and assign it to Beverage (AleScore inherits from BeerScore).
I am getting an error calling Beverage.Read(); immediately after.
/home/curlious/assignment7/src/beveragecreator.cpp:54: error: request for member `Read' in `((BeverageCreator*)this)->BeverageCreator::Beverage', which is of non-class type `BeerScore*'

Code:

#include "beveragecreator.h"
#include <stdlib.h>
#
#include "beerscore.h"
#include "alescore.h"
#include "lagerscore.h"

BeverageCreator::BeverageCreator()
{
   
}
           
BeerScore * BeverageCreator::CreateBeverage(vector<string>& BeverageMessage)
{  
   vector<string> Beverages;
   Beverages.push_back("Ale"); Beverages.push_back("Lager"); Beverages.push_back("Malt Liquor"); Beverages.push_back("Wine Cooler");
   
   int TypeIndex = 0;
   
   vector<string>::iterator TypeLookup;
   for (TypeLookup = Beverages.begin(); TypeLookup != Beverages.end(); TypeLookup++)
   {
      
      if (BeverageMessage[0] == *TypeLookup)
         break;
      TypeIndex++;
   }
   
   BeverageMessage.erase(BeverageMessage.begin());
   
   switch (TypeIndex)
   {   
       case 0:
          Beverage = new AleScore();
	  Beverage.Read(BeverageMessage); //problem here
          return Beverage;
       case 1:
         Beverage = new 
            LagerScore(BeverageMessage[2],atoi(BeverageMessage[3].chars()),atoi(BeverageMessage[4].chars()),atoi(BeverageMessage[5].chars()));
         return Beverage;
       case 2:   
       case 3: 
       default:
           break;
   }
}

Given that Beverage is a pointer, use the -> operator.
