Having trouble figuring out macros for 5e OGL Spellcasting NPCs

This is my first posting so please forgive the poor formatting. I have been following the tutorials by Taking20 on YouTube, and have started building up a monster manual. I'm now trying to create a spellcasting NPC, namely a Drow, but none of the macros I had set up are working.  For example, for an attack I have: /w gm %{selected|repeating_npcaction_$0_npc_action} But whenever I try running this on the Drow, it says:  No ability was found for %{Drow|Shortsword} Additionally, I tried setting up a macro to display its 3 innate spells.  %{selected|repeating_spell-npc_$0_spell} %{selected|repeating_spell-npc_$1_spell} %{selected|repeating_spell-npc_$2_spell} This returns with:  No ability was found for %{Drow|Innate-Spell} I'm not sure what I'm doing incorrectly, and am not quite familiar/comfortable enough with macros yet to debug it myself.

Which character sheet are you using? This sounds like the error you would get with a different character sheet that lacks those ability names.

I'm using the D&D for 5e by Roll20 sheet. The issue with the ability names only comes up when I make a new spellcasting NPC however, not when it's a standard NPC.
