Display highlighted data from Listbox in Textboxes

There are lots of errors, too many to post. I am going to start all over on this and use an array of structures, then go from there.

Are you new to the C#/Visual Studio compiler? What tends to happen is that there are errors that occur because of other errors. If you tackle them one by one from the beginning you might be able to sort them out. The ones you're not able to resolve you can post them here.
