I've been 2 days trying to do it, with no success. I need to send Tokens to 1300 addresses that participated in the Bounty/Airdrop and I can't send manually one by one, that would take a lot of time and money.

I've deployed that on the testnet using MetaMask and Solidity Compiler:

contract ERC20 { function transfer(address _recipient, uint256 amount) public; } contract MultiTransfer { function multiTransfer(ERC20 token, address[] _addresses, uint256 amount) public { for (uint256 i = 0; i < _addresses.length; i++) { token.transfer(_addresses[i], amount); } } }

Later I sent 1000 ERC20 Tokens to it and tried to call the multisend function in MyEtherWallet. Then I put the PrivateKey from my wallet and press "Write", but nothing happens
