I really appreciate all of the time and effort, and thought that has obviously gone into this answer.

I had already figured out the answer to the problem, and it is the same as what you have said here.
This is really cool, the way this has been answered!

The other thing I was doing wrong with this problem is that the array must be declared in the public area of the form (I am not sure of the correct name for that area).

The instructor’s requirement was that the array should only be populated one time, when the form loads. That means that the display click event needs to be able to access it, so it has to be declared in the public area.

Thanks again! Hopefully this information will help others who are learning VB.NET.

p.s. I am almost certain that it is impossible to “assign a range of values, such as 0 to 299, to a variable ” as I tried to do.

I know that a scalar variable can hold ONLY one value at a time.
