### Tell us what’s happening:

I tried to check for if the discount is a number or not, but the box doesn’t get checked. Instead, I checked the 9th box.. What’s the problem here?

### Your code so far

```py
def apply_discount(price, discount):
    if type(price) == int or type(price) == float:
        return(price)
    else:
        return('The price should be a number')

        if type(discount) == int or type(discount) == float:
            return(discount)
        else:
            return('The discount should be a number')

```

Welcome to the forum @tedevelynmosby

To help you debug, add these print calls after the function:

```auto
print(apply_discount(200, 50))
print(apply_discount(50, 0))

```

Happy coding
