Heading 3 not appearing in table of contents

I have set the levels appropriately under ‘Outline numbering’, yet only Heading 1’s and Heading 2’s only appear under the table of contents.

Using LibreOffice 3.4.4
Any ideas?

Edit:

Here’s a sample document:

Right-click Table of Contents and select Edit Index/Table. In the Index/Table tab set “Evaluate up to level” to a higher value.

oh my god, thank you, I don’t know how I did not notice that

That is the point… :slight_smile:

Please upload a sample document.

Thankyou so much
