Here are my two screenshots

The errors in the first screenshot just tell me to make the numbers final.

My question is how do I make the code only subtract. like it starts at 20, and goes down every time the button is clicked?

Thanks

Hereโs some code:

```
//gets text from userInput text field
int player = Integer.parseInt(userInput.getText());
//Generates the computers number
Random rand = new Random();
int min = 1;
int max = 3;
int number = rand.nextInt(max - min + 1) + min;
int playerAmount = playerTotal - player;
int computerAmount = computer - number;
//Will set text depending on user input
if (player >= 1)
{
outputLabel.setText("You have " + playerAmount + " stones left. I have " + computerAmount + " left.");
}
else if (player < 0)
{
outputLabel.setText("The number you chose is too small");
}
else if (player > 3)
{
outputLabel.setText("The number you have picked is too large");
}
else if (playerAmount == 0 || computerAmount == 0)
{
outputLabel.setText("The game is done, thanks for playing");
}
else
{
outputLabel.setText("Invaild Input");
}
```

and

```
int computer = 20;
//sets player amount to start from 20
int playerTotal = 20;
```

all I need is some help with figuring out the Global Variable in general
