Question: Im an absolute beginner in java and need help adding a string instance variable. I dont even really know how to ask my question but 

```
public class Account {
  private int AccountNumber;
  private int FirstName;
  private int LastName;
// ok here is where im stuck, i realize that Firstname and LastName are not integers but how else can i make a instance variable of them?           
  private double balance;
 public Account(double initialBalance, int getFirstName, int getLastName, int        getAccountNumber) {
//Int is not the correct type for FirstName and LastName but I dont know what else to call it. Any ideas?
    FirstName = getFirstName;
    LastName = getLastName;
    AccountNumber = getAccountNumber;
    }

```

Answer: 
`raw_input.replace(' ', '').isalpha`

You didn't call the function `isalpha`, only referenced it. Add `()`

`if first_letter == 'a' or 'e' or 'i' or 'o' or 'u':`

Is the same as:

`if (first_letter == 'a') or ('e') or ('i') or ('o') or ('u'):`

Which will always be True, as non-empty strings are considered True.

Change it to:

`if first_letter in 'aeiou':`

You also forgot to indent `print('The text you entered is invalid.')` at the bottom.
That final else block lacks a matching if. Omit the last "else: " and its likely to work.
