I'm not sure how to fit the conditional statement inside of the function, or what that statement should even look like.

script.js
```function max(1, 2){

}
``` An if statement looks like this:

```if(some condition) {
//do something
}
```

You can place if statements inside a function block (the two curly braces). It will check the condition once the function is called (e.g. max(input1, input2)). Ok, so first you have your function:

```function max (x, y) {
}
```

You can name the parameters whatever you'd like, just not a number. Inside the function you have your if statement:

```if (x > y) {
}
```

You need to use the same variables so that it references back to the function parameters. If you need to return a value, you use the return keyword:

```if (x > y) {
return x;
}
```

So your full function would look like this:

```function max (x, y) {
if (x > y) {
return x;
}
}
```

To compare two values, you enter your arguments when the function is called:

```max(1, 2);
```

In this example, the program is replacing x with 1 and y with 2:

```function max (1, 2) {
if (1 > 2) {
return 1;
}
}
```

Since it's frowned upon to give full answers, I'll let you figure out how to return y if it is larger than x. A hint is that right now the function doesn't know what else to do if the first condition is not met.

Here is how I would do it:

```function max (x, y) {
if (x > y) {
return x;
}
else {
return y;
}
}
```
