Multiple Data

Question:

Trying to create a simple table or form. Consist of orders from clients. I created 2 tables. One with the client info and the other table consist of orders. I linked both tables as a relationship. My problem is where how do I do the following:

1) How do I create a form and a table where I can input orders with different items on 1 order? example: Order 1 Laptop,hardrive,keyboard

2) How do I create a form where I can input the client info and the orders he want. Orders that have several items in 1 order.
