ASP.Net/C# - Inserting multiple records based on dates

hi

i have a customer form whose data is inserted into a table customer in a sql server .

The customerid field is an identity field . My query is this:

i have two date fields customer date and customer return date.

the customer return date field shows up only when a check box chkcustomerreturn is checked.

so if user enters customerdate as 10/25/2009 and customer returndate as 10/28/2009 and for the checkbox is checked

i want to insert three new records with the other information being same except for the customerdate field in the
table customer having the dates for the records as 10/25/2009,10/26/2009,10/27..10/28/2009.

if the checkbox was not checked since they can see only one date text field it would be only one record in the backend.

i hope you got what i want to say
