Code won't let me access specific parts of a dictionary

[signal valley]

this is the code I am trying to get to work

this is what is in the resource itself

this is the dictionary thing I am trying to refrence

this works so I know that the code itself works fine

this is the error I get when I try to run the program

no idea how to fix this or convert it into a proper string or whatever it actually wants from me

I forgot an important step, this is the purchase where the code is supposed to get the item name from
