You just have to declare the variable just after the conditional if statement with the var keyword. This way you'll be sure the scope of the variable is going to be inside the function If I remember well. Then as you are in the same scope, you can simply assign the string value you want if the condition is true, if(pushed).


function elevatorCloseButton(pushed) {
        var status="";
        if (pushed) {
            status = "I'll close when I'm ready.";

Thank you Geoffrey, I was stuck on this question. I guess I should re-watch this video again because I was not fully understanding.
