    function fund() public {
        require (msg.value.getConversionRate() >= MINIMUM_USD, "Didn't send enough eeeeth"); // 1e18 == 1 * 10 ** 18 
        funders.push(msg.sender);
        addressToAmountFunded[msg.sender] += msg.value;
    }

On this function I'm running into this error:

"TypeError: msg.value" and "callvalue()" can only be used in payable public functions. Make the function "payable" or use an internal function to avoid this error.

Can someone tell me what's going on?

Functions need to have the payable specifier to receive funds. The funds are usually contained in msg.value hence you have to add the specifier payable in your function declaration.

Change your function declaration to: function fund() public payable {}
