Crystal Reports Formula that counts the product type by packaging without

I have a product type that needs to counts the number of product types in boxes.
So if the product is Shampoo then how many boxes of shampoo or toothpaste how many boxes
What I want should look like this.
       Truck # 100
                                         Prell  :  20
                                        Crest : 48
                                        Floss : 52

Currently the data is in this format where the Products (Prell,Crest,Floss) are in a subreport with no way of counting the individual boxes. However at the primary report level I can count the boxes by product but do not know how to when I need to post them alongside the product types. As seen above. Can this be done...?

     Truck # 100
                        Total Boxes 120
                                                  Prell  
                                                  Crest
                                                  Floss
