Conditional cannot call method 'match' of undefined

1. Create a conditional
2. When changing conditional field (select box), a javascript error is thrown.
Uncaught TypeError: Cannot call method 'match' of undefined webform.js?mv8hfy:116
3. Error found on this line http://pastebin.com/SrZZ1m1f.

Also, fields are visible by default even when they should be hidden first.

Conditional is supposed to only show certain text boxes if the select box equals a specific value.
