problem trying to create a simple class

Question

Hi all, I'm getting an error message when I try to run the following class. The error message is: "object reference not set to an instance of an object." This error message is referring to variable "a" below when I try to increment it in the "for" statement "a++". Any suggestions would be very much appreciated. Thanks.
