Hello...!!!

database table=issue_details in which columns are issue_id is identity,book_tag_id,member_id,book_issue_on.due_date
database table=return_details colums are return_id identity,issue_id,book_returned_on,fine_per_day
database=membership_details columns are membership_id,membership_desc(gold,silver,platinum)
Now my return form is:book_tag_id=textbox1
member_id=textbox2
Issue_date=textbox3
returndate=textbox4
fine=textbox5
textbox5:-fine
membership_desc=silver,gold,platinum
fine_per_day for silver=30
gold=20
platinum=10
now what code i will write soo that when tag_id is filled in text_box 1
the fine according to membership_desc and return and due date...calculated fine get displayed automatically in text box 5
(due_date-returndate)*20 or 10 or 30
