Fehler beim Schreiben eines Vertrags auf Mist Wallet

Ich habe versucht, einen Vertrag abzuschließen, um Token gleichzeitig an viele Adressen zu senden, aber wenn ich möchte, dass der Vertrag Probleme in der Mist-Wallet hat, muss ich welchen Vertragscode verwenden?

CODE:

pragma solidity ^0.4.16;

contract Ownable {

  address public owner;

  function Ownable() {
    owner = msg.sender;
  }

  modifier onlyOwner() {
    require(msg.sender == owner);
    _;
  }

  function transferOwnership(address newOwner) onlyOwner {
    require(newOwner != address(0));
    owner = newOwner;
  }
}

interface Token {
  function transfer(address _to, uint256 _value) returns (bool);
  function balanceOf(address _owner) constant returns (uint256 balance);
}

contract AirDrop is Ownable {

  Token token;

  event TransferredToken(address indexed to, uint256 value);
  event FailedTransfer(address indexed to, uint256 value);

  modifier whenDropIsActive() {
    assert(isActive());

    _;
  }

  function AirDrop () {
      address _tokenAddr =0xe34c1960fbf05d4e08c19248491dfbcdbeab6e44; //here pass address of your token
      token = Token(_tokenAddr);
  }

  function isActive() constant returns (bool) {
    return (
        tokensAvailable() > 0 // Tokens must be available to send
    );
  }
  //below function can be used when you want to send every recipeint with different number of tokens
  function sendTokens(address[] dests, uint256[] values) whenDropIsActive onlyOwner external {
    uint256 i = 0;
    while (i < dests.length) {
        uint256 toSend = values[i] ;
        sendInternally(dests[i] , toSend, values[i]);
        i++;
    }
  }

  // this function can be used when you want to send same number of tokens to all the recipients
  function sendTokensSingleValue(address[] dests, uint256 value) whenDropIsActive onlyOwner external {
    uint256 i = 0;
    uint256 toSend = value;
    while (i < dests.length) {
        sendInternally(dests[i] , toSend, value);
        i++;
    }
  }  

  function sendInternally(address recipient, uint256 tokensToSend, uint256 valueToPresent) internal {
    if(recipient == address(0)) return;

    if(tokensAvailable() >= tokensToSend) {
      token.transfer(recipient, tokensToSend);
      TransferredToken(recipient, valueToPresent);
    } else {
      FailedTransfer(recipient, valueToPresent); 
    }
  }   


  function tokensAvailable() constant returns (uint256) {
    return token.balanceOf(this);
  }

  function destroy() onlyOwner {
    uint256 balance = tokensAvailable();
    require (balance > 0);
    token.transfer(owner, balance);
    selfdestruct(owner);
  }
}

und für hier füge ich den Adressvertrag oder die Adresse hinzu, die das Token enthält?

 function AirDrop () {
      address _tokenAddr =0xe34c1960fbf05d4e08c19248491dfbcdbeab6e44; //here pass address of your token
      token = Token(_tokenAddr);
  }
