Place a Boolean value between the parenthesis for the condition in this conditional statement.

Use the boolean value that will result in the message "This is true" appearing in an alert box.

It says as below: Bummer! Did you add true inside the parentheses of the conditional statement?

but i am confused.

script.js 
var c = false; 
var a = 10;
var b = 3;

if (a > b) {
  c = true ;
}

if (c = true) {
alert('This is true');
} else {
    alert('This is false');
}

Hi Bei, problem is in your second if statement in condition you are assigning value to variable c again instead of checking whether variable c is equal to true. But you can finish this challenge by simply putting true inside the condition. Code might look like this:

if (true) {
    alert('This is true');
} else {
    alert('This is false');
}
