How to set up existing project for Perforce version control

link textFirst off, I'm a newbie to version control so please bear with me. Secondly, I am a solo game developer and do all my work off my laptop. I am using Unity 2017.4 with the latest version of Perforce. With help from Perforce, I was able to get the Perforce server and client set up and configured on my laptop. So now I want to bring my current (and past) game projects into version control. I was referred to the community for help by Perforce. I've searched here on Answers and in the Forum (External Tools board) and found a couple similar situations to mine, but they were old (2015 and 2016 using Unity 4x. I can get a project file set up in a Perforce depot, and I can create a Perforce workspace from that depot. However, when I try and follow the Unity and Perforce documentation for integration, I get error messages. I've included screenshots of my configuration. I hope someone can advise what I've done wrong and what needs to be done to get things working. Thanks in advance.
