How do I get the drawPlayerIcons to work?

Hello,  I posted in the questions thread also but I'm not sure that's the right spot so I'm posting here as well.  Any help is GREATLY appreciated. 

I make simple missions for me and my 5 friends to play on occasion (so not the full wasteland).  They always complain about not being able to see each other.  In wasteland, everyone on your team/group has an icon when you press the windows key.  Through extensive searching, I found the drawPlayerIcons.SQF file here.  I copied it and placed it into my mission folder.  I load the mission and.....nothing.  Do I need to add something to the init.SQF file? If so, what?

How do I make it work?  This is just a simple 5 man mission....
