# Can anyone help me with my challenge attempt

heres the code that i wrote, im having trouble with the score part, how to add 1 score to the "score" variable if i quessed right, and remove 1 if wrong,

i put the else "score = 0" if question is not answered correct, but does'nt that set the whole score back to 0?

```var questions = firstQuestion + secondQuestion + thirdQuestion + fourthQuestion + fifthQuestion;

var firstQuestion = prompt("Whats the capital city of sweden");

var secondQuestion = prompt("Whats the capital city of Norway");

var thirdQuestion = prompt("Whats the capital city of Denmark");

var fourthQuestion = prompt("Whats the capital city of Finland");

var fifthQuestion = prompt("Whats the capital city of England");

var score = 0

if (firstQuestion === "stockholm") {
score += 1
} else {
score -= 0
}

if (secondQuestion === "Oslo") {
score += 1
} else {
score -= 1
}

if (thirdQuestion === "Kopenhagen") {
score += 1
} else {
score -= -1
}

if (fourthQuestion === "Helsinki") {
score += 1
} else {
score -= -1
}

if (fifthQuestion === "London") {
score += 1
} else {
score -= -1
}

if (score === 5) {
alert(" Congratulaions you earned a golden crown!");
} else if (score === 4 || score === 3) {
} else if (score === 2 || score === 1) {
alert("Good, you earned a bronze crown!");
} else {
document.write("You did not answer any questions right, you did not earn a crown!");
}
``` Hello Erdrag.

I think the problem here is a pure maths problem.

When you write score -= -1 you are in fact adding a point even if the answer is wrong. It is the same as score += 1, so it turn out that if you go wrong on every single question you actually score 2 in total.

Let me ask you a question:

when user's answer is wrong, do you want to add 0 to the points total or you want to subtract 1? I ask this because in the Stockholm question you go with zero, while it seems that in the other questions you want to subtract 1. Please note that in only the else code for Oslo actually subtracts.

Let me know if it makes sense.

Hey thanks for replying so Quick, yea i want to subtract 1 if a questions is wrong, i put the 0 in the Stockholm questions because i did not know if it was good to subtract 1 if you havent got any points, wouldnt that make the score -1? Hello Erdrag.

Yes that would make score = -1, but this is covered by the final else statement when you provide the result. So 0 and -1 would both write "You did not answer any questions right, you did not earn a crown!" on the document.

Vittorio

Hey again, lets say i answer the first questions wrong so it subtract 1 from the score, so now its -1 then i answer the second question right so i get +1 in score so now i have 0 in score, when i should have 1 So this means that you don't want to subtract 1 point when they go wrong with a question right? That's why I asked.

If you want to subtract 1 when they go wrong and add 1 when the answer correctly, in the case you just wrote the result has to be 0 and not 1. (-1 from first question and +1 from second question equals 0).

Otherwise, if you want to have score = 1 with a wrong answer + a right answer, you don't have to penalize them subtracting 1 when they go wrong; in this case you can just get rid of the al the else statement that subtract 1 if a answer is wrong (those are the one with score -= 1 inside).

Which one is the option you want?

Hey , i want to add 1 score if a question is answered correctly, and not give any point if a question is answered wrong,

thats why i did "if the question is answered correctly" score += 1 to add 1 score, (dont know if its the correct way to do it)

but i had problem to figure out how to do if you answered wrong, so i tried subtracting 1, but i did not work,

i tried to remove the else statements, so when a question is answered wrong it does not change the score, but when i had all questions correct, it said i got a silver crown in the end, so im not sure what i am doing wrong here.

Hello, i removed the score -1 at the else statements, and now it works, thanks for explaining!:) heres the code, tell me what you think about it:P

```var score = 0;

var firstQuestion = prompt("Whats the capital city of sweden?");

if (firstQuestion.toLowerCase() === "stockholm") {
score += 1;
alert("Correct, you have earned 1 point");
} else {
}

var secondQuestion = prompt("Whats the capital city of Norway?");

if (secondQuestion.toLowerCase() === "oslo") {
score += 1;
alert("Correct, you have earned 1 point");
} else {
}

var thirdQuestion = prompt("Whats the capital city of Denmark?");

if (thirdQuestion.toLowerCase() === "kopenhagen") {
score += 1;
alert("Correct, you have earned 1 point");
} else {
}

var fourthQuestion = prompt("Whats the capital city of Finland?");

if (fourthQuestion.toLowerCase() === "helsinki") {
score += 1;
alert("Correct, you have earned 1 point");
} else {
}

var fifthQuestion = prompt("Whats the capital city of England?");

if (fifthQuestion.toLowerCase() === "london") {
score += 1;
alert("Correct, you have earned 1 point");
} else {
}

if (score === 5) {
alert(" Congratulaions you earned a golden crown!");
} else if (score === 4 || score === 3) {
} else if (score === 2 || score === 1) {
alert("Good, you earned a bronze crown!");
} else {
document.write("You did not answer any questions right, you did not earn a crown!");
}
