I'm making an Alternate-Start mod for my own use with 30+ roles to choose from blah blah blah.

One of them is GAAARYYY! So the point is that the player will be identical to Gary.
Script:

	if CG00.Faction == 20		if Player.GetIssix Female			sixchange		endif			Player.addtofaction Vault108GaryFaction 1			ClearFactionPlayerEnemyFlag Vault108GaryFaction			Player.MatchRace LDGary1REF			Player.MatchFaceGeometry LDGary1REF CGMatchFace;			Player.setEyes LDGary1REF player;			Player.setHair LDGary1REF player			player.additem VaultSuit108 1			player.equipitem VaultSuit108			player.additem weap10mmPistol 1			player.additem weapknife 1			player.modav Charisma -9			player.moveto FSVault108Marker	endif

As you can see two commands are blocked out. I found them in GECK wiki but they don't work.

So the problem here is how I can force the player have Gary's eyes and hair.

EDIT: Also, is there a limit for variable numbers? There are total 34 variable numbers for CG00.Faction (Gary being 20), and I'm wondering if I've passed some limit and thus my scripts won't work.

I know nothing about the hair and eyes thing, but, I can tell you not to worry about variables. My variables in the Followers quest work fine. Pasted below to convince you on this point...
