parseInt() not working with prompt()

Hi, I can't seem to get the second question to work properly and increment the score by 1. I suspect the parseInt() method is not working properly, but I can't figure out why. Thanks.

var correct = 0;

var questionOne = prompt("What is the largest country in the world?"); if (questionOne.toLowerCase() === "russia") { correct++; }

var questionTwo = prompt("What is 10% of 5?"); if (parseInt(questionTwo) === 0.5 || parseInt(questionTwo) === .5) { correct++; }

alert(correct);

Hi Jonathan, the parseInt() method is used to extract integers from a string(which is anything between quote marks). Looking at your code you're trying to extract '0.5' which isn't an integer, it's a floating point number(decimal number). So you're to use the parseFloat() method instead. Happy coding :)
