Why is it not seeing the else statement?

var a = 10; var b = 20; var c = 30; if (a > b) { window.alert("<p>a is greater than b</p>"); } else { window.alert("<p>a is not greater than b</p>"); }

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

The else statement is fine. The issue is the string you are passing the alert method. You don't need to include <p> tags with the message. That is only done when using the document.write method due to the fact that it writes HTML directly to your webpage. The alert method just pops up a message, it does not involve HTML at all.

If you remove the tag like this:

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

Then your code will pass. Though it's also worth mentioning that you don't really need to include window. before the alert method. alert by itself is treated as an alias for window.alert in all browsers I know of.

Hi Anthony

Delete the "<p>" & "</p>" from the alerts.
