Not finding a skill added by Choicelist

[RobKamm]

Okay, I've got a strange one here. I'm using a #ChoiceList to add weapon skills to a template, ala what we've done in the DF templates. Some of the options include two weapons, others only one. The options that include two weapons work just fine, both skills show up and there is no error message. However, when a single-weapon option is used the skill appears on the character sheet's skill list -- but the template has a red-P indicating that something is missing. Needs/Check All claims that the skill added in the ChoiceList hasn't been added. The Logging screen has this message:

AA: I couldn't find {SK:Staff}. You'll have to add it manually.

AA is the name of the template (it keeps it at the top of the list so that I can get at it faster while debugging, I change the name once it is working).

The ChoiceList looks like (I've cut out some options for clarity, this generates the same error):

x(_
	#ChoiceList(_
	name(weapontypes),
	title("Combat specialty"),
	text(Choose your melee skill package.),
	picksallowed(1),
	method(bynumber),
	list(_
			"Smallsword and Buckler",
			"Smallsword and Cloak",
			"Smallsword and Main-Gauche",
			"Polearm",
			"Spear only" _
		),
	aliaslist(_	
			"{SK:Smallsword}=12pts, {SK:Shield (Buckler)}=8pts",
			"{SK:Smallsword}=12pts, {SK:Cloak}=8pts",
			"{SK:Smallsword}=12pts, {SK:Main-Gauche}=8pts",
			"{SK:Polearm}=20pts",
		             "{SK:Spear}=20pts" _
		)_
   	)_
),

Can anyone see where I've messed up? Thanks.
