I created a custom field that is a text box. It is to be used for a hyperlink.
If I use double-quotes (""), it breaks.
If I use single-quotes (' '), it works fine.
I'm not sure if this is an issue with CustomPress or Directory, but the custom field is tied to a Directory Listing CPT.
Here's a screenshot of the issue: http://screencast.com/t/fwkgXVMKHzt
