There is only one occurrence parameter, it is used for starting position.
So you can't use as 'the third <h2>'.
Add one more parameter to specify ending position, or change the place between 2 Position function.

Hello!

Remember that you can use more characters to get unique start and stop places. I would try having "</li></ul>
<h2>" as stop point.

best regards,
Ulf

Hello again!

I have also in some cases first found the text i wanted by first finding a bigger surrounding text, when i got that, it was easier to find the text I wanted inside the fist text. Perhaps you can use that method?

Regards
Ulf
