There has been a change in May allowing setting and posting multiple 
checkboxes in some cases. See how to use it here:


I believe Fox was also updated to handle those.

The current way to do this would be to set multiple default values, 
separated by spaces, like:

your PageTextVariable (PTV):
(:Hobby:Travels Music:)

in the form:
(:input default $:Hobby[] {$:Hobby}:)

(:input checkbox $:Hobby[] Travels:) Travels
(:input checkbox $:Hobby[] Photography:) Photography
(:input checkbox $:Hobby[] Music:) Music

No need to have (:if matchstring...:).

Note that a PTV cannot set multiple-checkboxes directly with (:input 
default source={$FullName}:), as there is no PTV "$:Hobby[]" with 
brackets, the PTV is "$:Hobby". That's why I set a default value as an 
intermediate step: (:input default $:Hobby[] {$:Hobby}:)

At the time I asked people to test and report any problems, and for 
ideas how to handle things, this is still possible.
