Hey,
I was just testing/learning with classes and i'm stuck at how to instantiate the class.
I've spent few days trying get myself out of this mess but i don't think i'm getting anywhere.

The picture below shows where I'm stuck at.
The sln file is attached below for reference if needed to.
Please help.
Thanks.

Here are the classes in the project.
I paste it here so that it is easier to see.
Thanks.
