# Capital M is wrong error?

#1

<Below this line, add a link to the EXACT exercise that you are stuck at.>
3. Computer Choice: Part1.
I’ve tried to complete the game as I find it easier than doing it step by step. I don’t know what is wrong with the Math.random code.

<In what way does your code behave incorrectly? Include ALL error messages.>
Oops, try again. Did you set var computerChoice = Math.random() ? The capital ‘M’ in ‘Math’ is important!

```

var userChoice = prompt(“Do you choose Rock, Paper, Scissors or Rope?”);
var computerChoice = Math.random();

if (computerChoice <= 0.24) {
computerChoice = “Rock”;
} else if (computerChoice > 0.24 && computerChoice <= 0.50) {
computerChoice = “Paper”;
} else if (computerChoice > 0.50 && computerChoice <= 0.75) {
computerChoice = “Scissors”;
} else {
computerChoice = “Rope”;
}

console.log("Computer choose: " + computerChoice);

var compare = function(choice1, choice2) {
if (choice1 === choice2) {
return userChoice = prompt(“The result is a tie!\nPlease make a new choice…”);
}

``````if (choice1 === "Rock") {
if (choice2 === "Paper") {
return "Paper Wins!";
} else if (choice2 === "Scissors") {
return "Rock Wins!";
} else {
return "Rope Wins!";
}
}

if (choice1 === "Paper") {
if (choice2 === "Rock") {
return "Rock Wins!";
} else if (choice2 === "Scissors") {
return "Scissors Wins!";
} else {
return "Rope Wins!";
}
}

if (choice1 === "Scissors") {
if (choice2 === "Rock") {
return "Rock Wins!";
} else if (choice2 === "Paper") {
return "Scissors Wins!";
} else {
return "Scissors Wins!";
}
}

if (choice1 === "Rope") {
if (choice2 === "Rock") {
return "Rope Wins!";
} else if (choice2 === "Paper") {
return "Rope Wins!";
} else {
return "Scissors Wins!";
}
}
``````

};

compare(userChoice,computerChoice);

``<do not remove the three backticks above>``

#2

the additional code in the exercise is the problem, this line:

``````var computerChoice = Math.random();
``````

means computerChoice now holds a random number, the checking script checks this, but you overwrite it, which causes the error. Maybe add a multi-line comment for the moment? multi-line comment:

``````/*
all the things which should be commented out
*/
``````

`/*` start the comment, `*/` ends it

#3

Are you saying I shouldn’t have the brackets, is that what is making it overwrite?

#4

Now, you overwrite the random number stored in computerChoice here:

``````if (computerChoice <= 0.24) {
computerChoice = "Rock";
} else if (computerChoice > 0.24 && computerChoice <= 0.50) {
computerChoice = "Paper";
} else if (computerChoice > 0.50 && computerChoice <= 0.75) {
computerChoice = "Scissors";
} else {
computerChoice = "Rope";
}
``````

Ok thank you, I have fixed the code now.
