running a template on a data object of pictures returned from facebook

Object {data: Array[8]}
data: Array[8]
__proto__: Object

sometimes the object returns an additional array of 'paging', sometimes it doesn't

How can I get something like this?

<script id="albums-photos-template" type="text/x-kendo-template">
# if (paging) { #
# if (paging.previous) { #
<a href='#= paging.previous #' class='albums-prev'>prev</a>
# } #
# } #
etc

I'm getting something like this

Uncaught ReferenceError: paging is not defined

Hi Phil,

You may use the typeof operator - if paging is not present, it will return undefined.
