Welcome to the Q&A Forum

Donford's answer is good then - they're probably ignoring those meta description tags as not relevant to the search query.  So it's not that they won't display them (assuming they're correctly set up) it's more that they're ignoring them as they're not relevant. From the horse's mouth: "Google will sometimes use the meta description of a page in search results snippets, if we think it gives users a more accurate description than would be possible purely from the on-page content." http://support.google.com/webmasters/bin/answer.py?hl=en&answer=35624
