i am looking to create an invoice in either MS-excel or MS-word. This invoice will contain several fields like invoice no., customer name, product info, quantity, Amount, Date, Address of customer, phone no. etc. The function of the invoice will be, to generate a unique invoice number, every time i open it, and then the vendor will mention the customer's info, product's info and click on submit button or save it. The info mentioned in the invoice will automatically be saved in the MS-Access database whenever submit button is clicked or the document is saved.

Thus, All the records of the customer will be saved in the MS-Access database. whenever i need to search for a particular customer, i should be able to search it from either invoice no. or any unique field for that particular invoice. I hope my query is explained clearly. please let me know the easiest way to do it. I do not have the vast knowledge about this subject, so give me suggestions that are understandable by a Novice.
