Hey I just ran into an error which isn't just resolving even though I tried my best
Feeling like crap right now. Here's the 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.

Please help me with this

function fund() public onlyOwner{
        require(msg.value.getConversionRate() >= MINIMUM_USD,"Did not sent enough");
        funders.push(msg.sender);
        addressToAmountFunded[msg.sender] += msg.value;
    }

You need to make fund function payable by adding payable keywork

function fund() public payable onlyOwner{
        require(msg.value.getConversionRate() >= MINIMUM_USD,"Did not sent enough");
        funders.push(msg.sender);
        addressToAmountFunded[msg.sender] += msg.value;
    }
