Traps in bags

[Felsai]

I am trying to make an addon to display the numbers of

Caged Mighty Clefthoof item number 119819
Caged Mighty Wolf item number 119815

How do I query to figure out if its in the bags and return how many. I havent found a tutorial for that if you know of one a link would be great.


The point of the addon is just so i don't have to keep my bags open to know how many traps i have finnished since i usually like to go out and get say 50 of them or 100. Hope that makes since.
