Counter Arty not working?

[tigerragrob]

How do I get it to work? Do I have to push a certain button? Never shows where arty is on my map..

First, and formost, This is a Mod, Not a Cheat. It will not SHOW you where Arty is, but if you learn the maps and places where arty likes to sit, it will produce a nice colored tracer from where Arty shot last.
