I'm a beginner.

I have a smart contract:

I'm a beginner and I have a smart contract:

I'm beginer.

pragma solidity ^0.4.0;

contract Coin {
    // The keyword "public" makes those variables
    // readable from outside.
    address public minter;
    mapping (address => uint) public balances;

    // Events allow light clients to react on
    // changes efficiently.
    event Sent(address from, address to, uint amount);

    // This is the constructor whose code is
    // run only when the contract is created.
    function Coin() {
        minter = msg.sender;
    }

    function mint(address receiver, uint amount) {
        if (msg.sender != minter) return;
        balances[receiver] += amount;
    }

    function send(address receiver, uint amount) {
        if (balances[msg.sender] < amount) return;
        balances[msg.sender] -= amount;
        balances[receiver] += amount;
        Sent(msg.sender, receiver, amount);
    }
}

I run on local console  : testrpc -u 0 -u 1

I run on Chrome console (result of compilation with https://ethereum.github.io/browser-solidity/)

And i try :

But nothing append :'( And i have no idea of why  !?

Work !! (Return @account[0])

Could someone write me the lines to copy paste into the console to execute an ether transfer with this smart-contract?
