Can't seem to find it and maybe it doesn't even exist....

Where in GECK can I give a condition that the player requires a tag skill?

For example, if I wanted to make a perk that requires having Energy Weapons or Barter as a tag skill.

Thanks in advance!

IsPlayerTagSkill [skill name]

Thanks for the quick reply.

I did find that and tried to make a test perk and it didn't work =(
I had as a condition:
Subject IsPlayerTagSkill EnergyWeapons == 1

Started a new game, took energy weapons as a tag and then didn't get the perk. Did I give it the right value?
