trying to build table, getting 'attempt to index a nil value' error

[ensiferumviking]

I'm still getting used to the lua table/key conventions. Here's the code that's causing problems:

local toonName=GetUnitName("reticleover")
PlayerInfoLogger.fullList[toonName]={}

That second line causes the error. 'toonName' is successfully resolving to a string. Can I not use a string variable as an index? fullList should be initialized to an empty table:

PlayerInfoLogger.Default={
  fullList={}
}
function PlayerInfoLogger:Initialize()
  --Define Saved Variables
  self.savedVariables=ZO_SavedVars:NewAccountWide("PlayerInfoLoggerSavedVariables", 1, nil, {PlayerInfoLogger.Default})

  --If there's a saved value, use that.
  PlayerInfoLogger.fullList=self.savedVariables.fullList
end

Is there a way to check that 'fullList' is indeed getting intialized? I've been able to verify the the Initialize function does get called.
