Excel 2003 :: Selecting Only Certain Items From One Sheet To Another?

Using Excel 2003

We have a spreadsheet set up showing a list of sales invoices, each invoice has the customer name and a customer reference assigned to it i.e B1, B2 etc

We want to set up another sheet that takes the sales invoice information but only picks up that which relates to a specific customer, i.e want a list of the invoices relating to B1

This will be done with a view to creating statements for each individual customer reference number which will just take info from these sheets B1,B2 etc
