order form in numbers

I have created an order form I would like to use at trade shows. I have a couple of tables created that help me capture specific information on the customer as well as their order... I have also created a separate list to help me quickly look at uncompleted orders...

how do I save the individual order sheet to be referred to at a later date and not lose that information and have a continual update to my list of orders?

Probably makes no sense! But Im frustrated.
