SQL Course, Stuck at lesson 5 (Resolved)

I'm and just started doing an online SQL course at:
http://sqlcourse.com/
The site let's you interactively test SQL lines.
They have a forum that I've posted to, but no-one seems to be 'home'

In lesson 4 you make a table.
I did that without a problem, and it showed me the table headers.
Here's my (masked) string

Code:

---

create table myemployees_jpXXX
(first varchar(30),
 last varchar(30),
 title varchar(30)
 age number(3),
 salary number(8,2));

---

In lesson 5 you start populating the table.

No matter what I try, I get this:
"Error occured. Recheck your SQL statement"

Here's my 1st Insertion string:

Code:

---

insert into myemployees_jpXXX
  (first, last, title, age, salary)
  values ('Jonie', 'Weber', 'Secretary', 28, 19500.00);

---

Did I make a mistake?
Or maybe their page isn't working right?

never mind, I found it.
I was missing a comma after this line:
title varchar(30)

So the table didn't have an age column.

I'm just surprised I didn't get an error when I did the create table call.
