pragma solidity 0.7.4;

 contract MyToken {
    address public minter;

    mapping (address => uint) public balances;
        minter = msg.sender;
    function mint(address receiver, unit amount) public {
        require(msg.sender == minter);
        balances[receiver] += amount;

oKAY this should be a simple piece of code that works that I watched from this video https://www.youtube.com/watch?v=1kMUPj5cP-0 as I'm learning how to deploy contracts (c# and c++ background) Its not making sense how this simple code isn't working. Please help me understand

I get the error "TestContract2.sol:12:37: DeclarationError: Identifier not found or not unique. function mint (address receiver, unit amount) public { ^--^ "

It's a bit cryptic, but there's a typo in your function parameters - unit -> uint:


function mint(address receiver, unit amount) public {


function mint(address receiver, uint amount) public {
