When I try to add the string argument I keep getting the error:

errorMessage(java.lang.String) in ProjectFile cannot be applied to ()

Code:
    public static void errorMessage(String defineError) {
        JOptionPane.showMessageDialog(null,
                                      "There is an error in the account file!\n" +
                                      "Please contact your branch to resolve this problem." +
                                      defineError, "Banking Error:", JOptionPane.ERROR_MESSAGE);
        System.exit(1);
    }
This is kind of urgent, so any help would be greatly appreciated
