Yeah David it does, but look at all the nice trys by people below. In fact some of them were very informative. I like Mike's suggestion, and it points out /null to me and wayne is kind enough to point out a quicker solution. Therefor I declare the question a success.

I mean, it still is a little surprising to me that there isn't an inbuilt way to test list or array membership.

Thanks for the alternatives guys.
