  function  public payable fund() {
        // Want to be able to set a minimum fund amount in USD
        // 1. How do we send ETH to this contract?

        require(msg.value.getConversionRate() >= MINIMUM_USD, "Didn't send enough!");  //1e18 == 1*10**18 = 1000000000000000000 (1 Eth in wei)
        funders.push(msg.sender);
        addressToAmountFunded[msg.sender] = msg.value;
        // What is reverting?
        // Undo any action before, and send remaining gas back
    }

On this function I'm running into this error

ParserError: Expected identifier but got 'public'

Can someone tell me what's going on? Thanks
