Circonians stambar tutorial, UI error
I've made it to part 3 of Circonians Stamina Bar tutorial and I am receiving the error

user:/AddOns/Dek01/Dek01.lua:39: attempt to index a nil value
stack traceback:
user:/AddOns/Dek01/Dek01.lua:39: in function 'Dek01:Initialize'
user:/AddOns/Dek01/Dek01.lua:29: in function 'Dek01.OnAddOnLoaded'
I've combed through my lua file trying to resolve this on my own but I am just not seeing what it could be.

Lua Code:
