My english is really bad... I'll try to explain.

In my Items table the recods are indexed by Item number. For each Order I'll haveone customer and several items.

I type the customer number and after I will type the items.
If in my items table I have:
I hope this helps you.
     ItemNo       Description
       1          Item 1
       2          Item 2
       3          Item 3
but in my Order I type 3, 1, 2, this sequence must not be changed.

Create another table...we'll call it OrderDetail
This table will hold your Order's Detail info and will have a unique id...OrderDetail_id of type integer. This will be your primary index/key.  As the user inserts an item you generate a unique id for each item...

Order (master table)
  Order_id: integer key
  Customer_id: integer

OrderDetail (detail table)
  OrderDetail_id: integer key
  Order_id: integer key
  Item_id: integer
  Quantity: float
