Need help with a "missing return statement"

Maybe I'm missing something, but the return is right there, plain as day...

This is the typical bank account program when learning about classes.

Code :

package lab03;
 
public class Account 
{
    public double balance;
 
    public Account(double amount)
    {
        balance = amount;
    }
    public Account()
    {
        balance = 0.0;
    }
 
    public void deposit(double amount)
    {
        balance += amount;
    }
 
    //THIS IS WHERE I NEED HELP
    public double withdraw(double amount) 
    {
        if (balance >= amount) 
        {
            //it says there's a missing return statement, but it's right here
            return balance -= amount;
        }
 
        else
        {
            System.out.println("Insufficient funds");
        }
    }
 
    public double getBalance() 
    {
        return balance;
    }
 
}
