Can somebody help me and find my error?

const getuserchoice = (userinput) => {
userinput = ‘rock’;
userinput = userinput.toLowerCase();
if (userinput === ‘rock’ || userinput === ‘paper’ || userinput === ‘scissors’){
return userinput;
}else{
console.log(‘Error! Undefined userinput please try again!’)
} };
console.log(getuserchoice())
const getComputerChoice = () => {
const randomNumber = Math.floor(Math.random() *3);
switch (randomNumber) {
case 0:
return ‘rock’;
case 1:
return’paper’;
case 2:
return ‘scissors’;
}}
console.log(getComputerChoice())
const Winner = (userChoice, computerchoice) =>
{
if (userChoice === computerChoice) {
return ‘This game is a tie!’
if (userChoice === ‘rock’){
if (computerchoice === ‘paper’){
return ‘Sorry Computer Won’;
