Text Game Inventory/Error

sadelbrid (19)
Okay so I'm making a text based game. I decided to put an inventory in using boolean variables. When I run the program it says that "a function definition is not allowed before '{'." The error is given at the line holding the first open curly brace for the inventory function. Please help Im so confused.

Because functions can't reside within any other function. You need to move the function outside of whatever function it resides in, and "Call" the function from within another function to get it to behave correctly.
