Device Hub Action for move screen

I am trying to add an action on the move screen to print a report via device hub. I was trying to follow the Acumatica post below and modify it for my needs . I am also including some others that i tried to use to help me, but i am clearly doing something wrong. I have very little knowledge of C# so its very possible it is a simple error that I dont know about. Below is my entire code. Any help would be greatly appreciated.
