Can't very contract on created in Ethereum Wallet using Etherscan,

Question

Used the following code, put it in to deploy new contract.

When I try to verify the code on etherscan it says it doesn't match the code of the contract?

Here's the Etherscan Link:

https://etherscan.io/address/0x84f7f794867642a47ce577fe0d9745da6ac37c44

And here's the code I inserted in the deploy contract part of the Ethereum wallet.

pragma solidity ^0.4.16;

contract MyKidsEducationFund {
  string public constant symbol = "MKEF";
  string public constant name = "MyKidsEducationFund";
  uint8 public constant decimals = 18;

  address owner = 0x3755530e18033E3EDe5E6b771F1F583bf86EfD10;

  mapping (address => uint256) public balances;

  event Transfer(address indexed _from, address indexed _to, uint256 _value);

  function MyKidsEducationFund() public {
    balances[msg.sender] = 1000;
  }

  function transfer(address _to, uint256 _value) public returns (bool success) {
    require(balances[msg.sender] >= _value);
    require(_value > 0);
    require(balances[_to] + _value >= balances[_to]);
    balances[msg.sender] -= _value;
    balances[_to] += _value;
    Transfer(msg.sender, _to, _value);
    return true;
  }

  function () payable public {
    require(msg.value >= 0);
    uint tokens = msg.value / 10 finney;
    balances[msg.sender] += tokens;
    owner.transfer(msg.value);
  }
}

It's important to match the compiler version and select optimization on/off exactly as everything was when the contract was compiled and the bytecode was generated.

Your use of ^ in the pragma makes it a bit ambiguous because it might have been compiled with any later version of the compiler.

With a little guesswork, I got it to verify with

• Compiler Version: v0.4.16+commit.d7661dd9
• Optimization Enabled: 1

It's done. No warranty ;-)

Hope it helps.
