Counter not counting down

Can someone take a second look at my code. The code is fine up until I put in the second counter, this line in particular "var question - =1;" I am going about it just as in the video however JS Bin is telling me that I am missing a semicolon in that line. Can someone show me where? Thx

var visitor = prompt("Hi! What is your name?");
var message = "Hello "+ visitor.toUpperCase() + " Welcome to the Q and A sessions, we are so please that you can join us.";
alert(message);
document.write("We will be asking you a series of five questions. The more questions you answer the bigger the prize. <p>READY!</p>");
document.write("<p>Here goes your first question</p>");
var question = 4;
var questionLeft = "[" + question +  " Questions Left]";
var one = prompt("Is Batman and Superman brothers? " + questionLeft);
if (one === "yes"){
    alert("That's correct")
} else {
    alert ("Wrong! Better luck next time<");

}
var question - =1;
var questionLeft = "[" + questions +  " Questions Left]";
var two = prompt("Is the grass really greener on the other side? " + questionLeft);
if (two === "yes"){
    alert("That's correct")
} else {
    alert ("Wrong! Better luck next time");

}

:point_right: You seem to have a stray minus sign (-) on this line:

var question - = 1;

The message about the semicolon is misleading. Just remove the stray minus.

Now that I look at it the var in front of question is recreating that variable, I think. Causing an error BECAUSE I don't think you can -= on a newly created var.

I did exactly what was in Dave video regarding a counter down so I am now a little confused as to why it's not working know. var question - = 1;

I commented out

// var question -=1;
// var questionLeft = "[" + questions +  " Questions Left]";

and it got rid of the errors. But I don't know why and without those lines your missing part of the functionality I think.

  • I tried something else
  • I think questions should be question
  • and var is unnecessary in front of question -=1;

it seems to works w/out errors after that
