There are a couple of steps you need to take to get this working:
Firstly, on line 281, change input_type to location_type.
Secondly, make sure each of the values in the "Name your input" dropdown correspond with the names of the place types. So, "OrganizationCommunity" on line 272 should match the place_type name on line 33. The values in the dropdown look good, make sure the place type titles match up. If you don't do this, Shareabouts doesn't know which location type matches up with the styling.
I am in the #shareabouts irc channel on irc.freenode.net
if you want to chat through these changes.
