<In what way does your code behave incorrectly? Include ALL error messages.>
My code seems to run correctly and display in the window whether the user wins or loses accurately, but I keep getting the error report
“Oops, try again. Your code returned ‘paper wins’ instead of ‘undefined’ when the inputs are scissors and paper.”

Can anyone tell me where I am messing up in my code? Thank you for the help.

```

var userChoice = prompt(“Do you choose rock, paper or scissors?”);
var computerChoice = Math.random();
if (computerChoice < 0.34) {
computerChoice = “rock”
} else if(computerChoice <= 0.67) {
computerChoice = “paper”
} else {
computerChoice = “scissors”
} console.log("Computer: " + computerChoice);
var compare = function(choice1, choice2){
if (choice1 === choice2) {
return “The result is a tie!”;
}
else if (choice1 === “rock”) {
if (choice2 === “scissors”) {
return “rock wins”;
}
else {
return “paper wins”;
}
}
else if (choice1 === “paper”) {
if (choice2 === “rock”) {
return “paper wins”;
}
else {
return “scissors wins”;
}
}
else if (choice1 === “scissors”){
if(choice2 === “rock”) {
return “rock wins”;
}
else {
return “paper wins”;
}
}
}

compare(userChoice, computerChoice);

@tsieg144,
It is as the Oops-message is stating…
Who wins,
if choice1 === “scissors” and choice2=== “paper” ???

Please read

and concentrate on:

  • the creation of the compare function
  • the truth-table
  • the build of the IF ELSE-IF statement structure as part of the compare FUNCTION-BODY
  • the execution of the compare function (keeping in mind that the return statement is used )
