If you look at how you're increasing your score each question:
correctAnswers = +1;
This is actually assigning the value positive one to the variable and replacing whatever was in it, not adding to it. the shorthand for variable = variable + 1 would be:
someVal += 1
Also have a look at that first question - you call capitalize on a string you'll then pass to parseInt to ensure it's a number ;)
Hope it helps!
PS as Steve said, if you put your code wrapped in 3 backticks like this:
```javascript
// Your JavaScript code here...
```
Then if will appear formated and easy to read, like this:
var correctAnswers = 0;
var talking = prompt("when donald trump ruled America?.");
if (parseInt(talking) == 2016) {
correctAnswers = +1;
} else {
alert("sorry you've got it wrong")
}
var talking_1 = prompt("who's the CEO of google?");
if (talking_1.toUpperCase === "sundar pichai") {
correctAnswers = +1;
} else {
alert("sorry you've got it wrong");
}
var talking_2 = prompt("what is the Biggest oceans in the earth");
if (talking_2.toUpperCase === "pacific ocean") {
correctAnswers = +1;
} else {
alert("sorry you've got it wrong");
}
var talking_3 = prompt("who made facebook?");
if (talking_3.toUpperCase === "michael zuckberg") {
correctAnswers = +1;
} else {
alert("sorry you've got it wrong");
}
var talking_4 = prompt("who made DropBox?");
if (talking_4.toUpperCase === "dave zuckberg") {
correctAnswers = +1;
} else {
alert("sorry you've got it wrong");
}

Courses Plus Student 9,155 PointsThank you very much for your answer, jon mirow but i have another question, How do i fix this problem? when i preview the results and i type in the right answer it say's to me that i'm wrong, for example
like this question:When donald trump ruled america? and i say 2016 and it says that i'm wrong what's wrong with this code?
and if you don't know that what did i type in the workspace. here's the code==>
var talking = prompt("when donald trump ruled America?.");
if (parseInt(talking) == 2016) {
correctAnswers = +1;
} else {

9,864 PointsHmm, I can't replicate that error on that code sorry.
I've added two alerts to your code above to demonstrate:
var talking = prompt("when donald trump ruled America?.");
if (parseInt(talking) == 2016) {
correctAnswers = +1;
alert("right");
} else {
alert("wrong");
}
If you copy that, press ctrl+shift+j in your browser and paste that into the console then hit return, you should see that it is working. Are you sure it's this question that isn't working in your workspace?
