Your problem is that you don't need to define _this as a variable and assign it parameters. His name is Mikie J so that's what the code will return as the parameters. All you need to do is take "_this = [MikeJ,MikeJ,1];" out of your script. It's not working because you're trying to call the target off the addaction, which should be you. But because you tried to define _this as a variable it's not working properly.
I hope that somewhat made sense. Basically take out that first line and your fine. In game it will show you you're arma profile name in the hint, not Mikie J's.
