將 ETH 發送到測試網上的合約時出錯

我正在嘗試將 ETH 發送到我剛剛創建的合約中，但我遇到了錯誤

pragma solidity ^0.4.6;
contract Owned {
   modifier only_owner {
       if (msg.sender != owner) return; _;
   }

   event NewOwner(address indexed old, address indexed current);

   function setOwner(address _new) only_owner { NewOwner(owner, _new); owner = _new; }

   address public owner = msg.sender;
}

有人知道發生了什麼嗎？

我認為任何接受 Ether 的函式都應該設置為“payable”
