calling functions

The instruction says beneath the max function call it with two numbers and create an alert dialog box . The problem is when i do that, i get a message that the code is no longer passing. Any idea please?

script.js 
a=1;
b=2;

function max(a,b){
if(b>a);
  max(1,2);
alert(Math.random(1)*2):  
return (b);
}
alert(Math.random(1)*2);

Once you pass task 1, you should not make any changes to the function. In task 2 you just call the function from new code you add below it.

There are several issues now that prevent the function from working, including:

  • an "if" statement should not have a semicolon after the conditional expression
  • the function should not call itself
  • there should be two different returns, one will be used based on the comparison
  • there should be no "alert" call inside the function

And when you do create the alert and call the function, you won't need to use "random".
