add a conditional statement that test if the value in variable a is greater than the variable b. if it is a pop up alert with message a is greater than b. also add is greater else clause that pops up the message a is not greater than b.

script.js 
var a = 10;
var b = 20;
var c = 30;
if (" answer === " var a" > " var b ") {
     windows.alert ("var a is greater than var b") ;
} else { 
  windows.alert ( " var a is not greater than var b");
}

First off, your conditional statement looks like you're trying to format a string for printing ... but to actually compare two variables you only need their names and the comparison operator. In this case :point_right: (a > b)

Then, when you print your alerts, your strings are a bit different than what the challenge asked. They need to be exactly the same for the checking routine to recognize them.

And finally, you wrote "windows" (with an extra "s") instead of "window" when calling the alert. You can fix it, but if you want you can also remove it entirely since the properties and methods of the window object are accessible just by name.

While that code may get a "pass" from the checking routine, that's actually not what the challenge asks for, for some of the reasons I discussed in my hints. The solution based on the instructions is actually a bit simpler (hint: no concatenation is needed).

Plus I think most folks get a better learning experience arriving at the final code themselves instead of plugging in explicit code solutions.

But your desire to help is great. Please take my comments merely as suggestions.
