syntax error?

Add a conditional statement that tests if the value in the variable a is greater than the value in variable b. If it is, pop up an alert with the message 'a is greater than b'; also add an else clause that pops up the message 'a is not greater than b'.

it says i have a syntax parse error

thanks

script.js 
var a = 10;
var b = 20;
var c = 30;

if (a > b){ alert("a is greater than b" )}

} else { (alert "a is not greater than b")

     }

Hi Sarah,

In your second alert, your parenthesis is incorrectly placed. Also you have a curly brace too many just before the else. And even though the code will run then, it's a best practice to put the semi-colon after each statement.
