I am currently using the code

                            // allow user to tip a set amount.
                            let tipAmount = window.web3.utils.toWei('.1', 'Ether')
                            console.log(event.target.name, tipAmount)
                            this.props.tipVideoOwner(event.target.name, tipAmount)
                          }}

Is there a way to make the 0.1 Eth a custom amount set by the user?
