Hi, I need help with a thing in WorldCraft. Not entirely on topic, I know, but it's almost programming...

I need to edit the FGD file for HalfLife (not Op4). I want to add an option to select which head the Monster_human_grunts have. You know, like the red beret or the cigar smoker. I tried to add body (...) (can't remember the exact syntax now), but that didn't work.
How do you do this?
