Hello everyone...
I'm trying to deploy an ether contract but I got this error:

Functions in interfaces should be declared external.
interface tokenRecipient { function receiveApproval(address _from, uint256 _value, address _token, bytes _extraData) public; }

The code source is : (Advanced Modal)

Can anyone help me? I would appreciate it!
