You would need to create a new child table with fields for "customer no." and "salesperson code" - that way you can set any number so salespeople per customer. I would normally then create a sum type flowfield on the customer called "No of Salespeople" with a drilldown onto the child table. Of course you would also need to amend other related stuff, e.g. reports etc where you want to show all the salespeople linked to each customer.
