3. Incorporate the social media links into your site’s footer. Include the code in a partial.

I’m stuck and I think it’s a scoping issue.
I pasted the ul block from contact.html into a partial I call social.html

<ul>
  {{ range .Site.Data.socialmedia.accounts }}
    <li><a href="{{ .url }}">{{ .name }}</a></li>
  {{ end }}
</ul>

social.html is getting picked up in the footer.html partial

<footer>
    <small>Copyright {{now.Format "2006"}} {{ .Site.Params.author }}. {{partial "social.html"}}</small>
</footer>

but is just rendering a blank unordered list in the output source
