Sending out an alert with 2 numbers from my argument...

I dont know what the alert is supposed to look like. I have tried multiply variations and have no clue what im doing wrong. :(

script.js 
function max(num1, num2){ 
  if (num1 > num2) {
    return num1;}
  else if (num2 > num1) {
    return num2;}
}
alert( max(num1, num2));

OK. then just :

 function max(num1, num2){ 
  if (num1 > num2) {
    return(num1);}
  else if (num2 > num1) {
    return(num2);}
}
alert(max(3,5));

3 and 5 is just for example you can put any numbers when you cal the function.

Hi Andrea,

 function max(num1, num2){ 
  if (num1 > num2) {
    alert(num1);}
  else if (num2 > num1) {
    alert(num2);}
}

If num1 is larger, then alert box with(num1) will appear ,if num2 is larger alert(num2) will appear. happy coding

hey! that wont work either bc they had me use the return function to return the proper number, now these are the next set of directions!

Beneath the max function you just created, call it with two numbers and display the results in an alert dialog. Pass the result of the function to the alert method.

For example, to display the results of the Math.random() method in an alert dialog you could type this: alert( Math.random( ) );

num1 and num2 are just a arguments(something like placeholders) for real numbers you gonna put when you call the function. You could name them whatever you want , it doesn't matter. But you should try to give them a name in the context of a function, to make it easier for you.

You're welcome
