Add a conditional statement that tests if the value in the variable a is greater than the value in variable b. If it is,

if(parseInt(a)>parseInt(b)) { //display alert } else { //display alert }

//if something wrong here?

var a = 10;
var b = 20;
var c = 30;
if(parseInt(a) > parseInt(b))
alert('a is greater than b');

alert('a is not greater than b'+parseInt(b));

You wont need parseInt here.

These variables are already numbers, parseInt is for when you have strings and need to convert them to numbers.

Also, the challenges are picky about code they provide to start with. Don't change any of it unless the instructions tell you to specifically.
