I want each NFT to cost .02 ETH to mint. There is a constructor uint256 variable called price, but I'm not sure what to do with it since it doesn't correspond to eth.
I just need to know what to add to the 'purchase' function in order to make it cost a certain amount PER nft. Meaning it'll be multiplied if they mint more than 1 in the transaction.
Here is the contract: https://rinkeby.etherscan.io/address/0x3F4d03C071bB0C2B7748417ED03D04C034687013#readContract
