car_speed = 50
speed_limit = 45

if car_speed
  flash_car_speed
else

end

Hey Sara, There is a problem with your "If" statement. As of right now, there is no boolean value being tested. Using "If" statements, just about any value that isnt 0 is going to return "true". Your if condition currently is car_speed... which means you're asking "if 50" to the computer. That will return true. Therefore, regardless of what you put in the 'else' condition, you will always "flash_car_speed". I'm assuming that you want to check if the car speed exceeds the speed limit. So your if statement should be this:

if car_speed > speed_limit

and then complete the conditional statement. Good luck!

Hi Sara - I think under else you just need to put in a call to the method display_car_speed. I am not really sure why that method was given in the Task 1 Question and not in Task 2 - but hope that resolves it
