Having Trouble With Defining a Local Site With a Testing Server

I have the latest version of Dreamweaver CC 2018 running on Win 10 Pro.

I am having a lot of trouble defining a local site with a testing server. I am using Wamp64 and my file structure as far as how I click through using my computer is this: C:/wamp64/www/seanvzwebguy/a3  My a3 is where my assets folder is and two php files index.php and results.php are that I want to be using that folder 'a3' folder where the two php files are.

This is how I pull the site up with wamp64 running: http://localhost/seanvzwebguy/a3/index.php

What do I choose for my local site folder given the above?

Where should I choose for my server folder?

Do I use the above local server address for the site definition or another one? If so, what should I type in for the web URL?

I am connecting using: Local/Network

My server model: PHP/MySQL
