Lesson 3: withdraw function error

[javierxvi]

Hi! I'm getting this error and can't compile.

You need to cast msg.sender to address payable.

See: https://docs.soliditylang.org/en/v0.6.0/types.html#address

[AlbertoSinigaglia]

... so use payable(address(...)) to cast it to be a payable addresses

[javierxvi]

Doesn't work :/

Cast msg.sender

[davidyuill27]

You’re casting the wrong variable. You want to cast msg.sender because that is type address not address payable. Write payable(msg.sender).transfer (…)
Think of it as msg.sender is type address. Address does not have transfer function, address payable has transfer function.
