# Idk how to do this challenge and need help on how to get isGreater Function to only have one parameter.

Im Confused

enum.swift
```enum Coin: Int {
case Penny = 1, Nickel = 5, Dime = 10, Quarter = 25

func isGreater(currentValue: Coin, newValue: Coin) -> Bool {
return currentValue.rawValue > newValue.rawValue
}
}
```

Hello Ricardo: This is an easy one, I know I know, you are learning and it will get easier for you as you go. Trust me, I was there !

Challenge says : Modify the isGreater function to only accept one parameter. Keep the newValue parameter and remove the currentValue parameter because you can retrieve the existing value using the keyword self

```enum Coin: Int {
case Penny = 1, Nickel = 5, Dime = 10, Quarter = 25

func isGreater(currentValue: Coin, newValue: Coin) -> Bool { // Erase currentValue
return currentValue.rawValue > newValue.rawValue  // use self.
}
}
```

This is how it looks:

```enum Coin: Int {
case Penny = 1, Nickel = 5, Dime = 10, Quarter = 25

func isGreater(newValue: Coin) -> Bool {
return self.rawValue > newValue.rawValue
}
}
```
