I notice that the in-text citations don't match the sources, for example Turnbull is cited, however he doesn't appear in the sources. Also, in order to get correct formatting, you need to put the citation info between the <ref> </ref> tags. Then, underneath the sources section, you don't write anything, just simply put in <references/> and they will all appear, correctly formatted.
Here is an example:
My name is bob<ref>I'm a monkey</ref>
==Sources==
<references/>
The result is:
My name is bob[1]
Sources
- ↑ I'm a monkey
