Question

Getting an error with my for loop.  How do I correct it?  I am supposed to: Continuously prompt for the number of minutes of each Rental until the value falls between 60 and 7,200 inclusive. For one of the Rental objects, create a loop that displays Coupon good for 10percent off next rental as many times as there are full hours in the Rental.
