i think i have lots of problem
let me ask in sequentially...
if u run the program u will get the customer id text box with three button which are ok,calculate and print button.
when u enter the customer id and pressed ok then in tabular format u get all the detail of that customer with their news paper name
and in each news paper row u will find separate column like Sunday,rate,Saturday,rate,other day ,rate column.ok
do u get uphill these....
