Zsoldout: Bad usability in SXSW signup form

I'm trying to book a hotel for SXSW and I see that the Hampton Inn is available to Gold, Interactive, and Film registrants. I know Andy had told me that it was sold out so I'm feeling great (someone must have dropped out!) Not believing my luck, I give Andy a call to double-check that it's the same hotel then hastily hang up to finish my order before someone else gets it.

So, I click on the Bedding drop-down and see "zsoldout(3/7-3/11)"
