ERC721 in Game Openzepplin

Ethereum Game Programming
#1

I have created an ERC721 Contract and put it up on Ropsten just for testing. (here is the contract address:0x4D650FeB68b26B1f9F16a85e965d935e1A01BEb7). I used openzepplin for all of the actual contracts in fact I didnt change anything and the main contract I am interacting with is below. So Ive written some code to interact with it using Web3. I try the awardItem function and nothing really happens. I am confused cause I thought a function that would need to do any calculations would require it to be payable and to create a transaction. But looking at the base code they have I dont see payable anywhere. Is this normal or am I missing something really important? I ran the awardItem function several times but it seems like it doesnt actually do anything and I cant figure out what the tokenID exactly is, looks like its just 1. At any rate, any ideas or suggestions would greatly be appreciated!!
