I'm trying to get the products and quantity selected in a subform and put them in a map.

Here are my forms:

Form 1: OrderForm:

Fields:

      1.Name (Single_Field)

      2. Products (Subform - Form 2)

Form 2: ProductsForm

Fields:

      1.Product Name (Dropdown Lookup Field to Form 3)

      2.Quantity (Single_Field)

Form 3: Items (Here is where I insert the products into the system, the user is not able to see this form)

Fields:

      1.Item Name (Single_Field)

On submit in the OrderForm, I want to fetch the Name, and all the Products and Quantities the user inserted and put them in a map. I'm really new to this, so I'm still getting a feel for this. Here is what I have so far:

2. myMap = Map();
3. ThisOrder  =  Untitled_Form  [ID == ID];
4. TheProducts = ThisOrder.Products;
5. for each val in TheProducts
6. {
7.     myMap.put(val.Product1); //Product1 is the name of the ProductName field
8. }
9. info result;

The info is showing null. Can someone help?
