Hi,

I'm adapting the lending library template file to work with our library which lends out items to students.

I'd like to set up a calculation so that a 20p fine is charged for each day that an item is kept after the due date. The maximum fine would be

I'm not sure what the p stands for (pence?), but your calculation for FineAmount would be something like Case( Get(CurrentDate) > DateDue and not Status = "available"; Min( 0.2 * (Get(CurrentDate) - DateDue); 2 ) ).

Thanks for that, I'll give it a go.

Yes, I confess, I'm a Brit.

I should add that the calculation would need to be unstored in order to update each day.

how could i get the calculation to stop at the 2.00 maximum fine?

The Min function should do that for you. It returns the minimum (smaller) of the two numbers.

Thanks a lot for that!

Interestingly enough, once I add the asterisk, I can no longer access the Storage Options. So I would suggest entering Case( Get(CurrentDate) > DateDue and not Status = "available" ; Min( (Get(CurrentDate) - DateDue); 2 ) ) first, setting the Storage Options to 'Do not store', and then adding the "0.2 *" portion.
