Hello, I am creating a test crowdsale smart contract on the ropsten network. When I past the code on the "deploy contract" section, on the right of the page appear the following error, someone can help me?

Could not compile source code.

No visibility specified. Defaulting to "public".
function transfer(address receiver, uint amount);
