i have this problem on how to calculate the amount due in our system in VISUAL BASIC.NET .
in returning module, (this is for penalty purposes), if the borrower didn't return the book on time, the system must automatically generate the amount due .
one daY is equivalent to 10(ten) pesos.
so if the borrower didn't return the book with 2 days. the amount due must be 20.00 pesos.
thank you very much to those who can answer my wonderful question..
btw..what i need is the formula.. an example code .. :)
