OBSE AddToLeveledList not recognizing creature lists?

[LittleBaron]

Firstly, this is my first time using these forums so forgive me if this question is misplaced.

 

I recently successfully added armor items to LL's dynamically using the OBSE script function AddToLeveledList.

 

Now, I have made two new creatures, which I want to add to LL1Undead100 etc. but I can't get it to compile b/c I get the "invalid item" error message... it specifies the Leveled List as the invalid item, not the object creature I am trying to add.

 

Is this like a container? I.E. I cannot really change the creature LL forms, just specific instances of them? If so, that sucks.

 

Thanks in advance for your wisdom.
