Parse Error for Using Comparison Operators

What am I doing wrong when parsing?

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


if (var a > var b){
    alert("a is greater than b");
}
else {
   alert("a is not greater than b");
}

Hi Diane,

The var keyword is only used to declare a variable. You don't have to use "var" on each variable in the if condition.
