Change the value of powerPoints to 5. Then create an if else statement such that when 'powerPoints' is less than 3 'hasB

i am stuck in this review

variable_assignment.mm 
bool hasBonus;
hasBonus = powerPoints
int powerPoints;
powerPoints = 5 ;

if (powerPoints < 3 ) {
  powerPoints = hasBonus;
}
else {
  powerPoints = hasBonus;

You're mostly on the right track! The problem here though is you are setting the value of hasBonus, which is a Boolean, to the the value of powerPoint, which is an Integer. Also, the problem does not ask you to set them equal to each other.

(Also, you can't reference variables before they're officially declared.)

The if/else conditions look correct, so aim for making sure hasBonus is set to the correct conditions.

Hint: Booleans only have 2 possible values.

As Oluwatobi said, you're mostly on the right track. So you've declared you're two variables, but you cannot assign powerPoints (an int) to hasBonus (a bool) . Delete that line.

You're checking for the correct thing in your IF statement, but then you're assigning hasBonus to powerPoints. Instead, you should be setting hasBonus to either true or false.

Once cleaned up, your answer should look similar to the below. Keep grinding. It'll come to you. 

bool hasBonus;
int powerPoints = 0;
powerPoints = 5;

if (powerPoints < 3) {
  hasBonus = false;
} else {
  hasBonus = true;  
}
