You didn't go step-by-step, that's your main error.

Here is how one tabber looks like:

Now three tabbers at the same level.

As you see, |-| is a divider between tabbers, and if there is only one taber level, then you need just one pair of closing brackets }}

Let's add the second level. To do that, you need to add a tabber within the content of the parent tabber.

In tab 1 I replaced all content with the child tabber, in tab 2 I added a tebber after the content, and in tab 3 I added two tabbers separated by a divider.

Just don't forget to count closing brackets and don't add more than one tab without checking the results and everything will be fine.
