What is wrong here?

I did use the >-sign?

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

To access the value of a variable you simply type the name of that variable. 

var a = 10;
alert('a'); // -> would print out the string -> 'a'
alert(a);   // -> would print out the value of the variable -> 10

After removing the quote marks there is still one thing that has to be changed: Because you don't want to create a new variable but only access the already existing variable, you have to remove the var keyword.
