, it looks like there's an error in the code for the form. There is also an error from the map that says you don't have a valid API key installed, so it's possible that the maps error is causing a conflict; it may be solved by making sure your API key is correct in the map widget.
I created a api key for the map widget and the problem still happens. Like i said above, the form works very fine in other themes, so i guess there is something make conflict with this theme, do you have any other idea?
Also I contacted to the support staff of "Caldera" and they said me that going to see if they can do something and that feel me free to give you his email [email protected]
other thing, I migrated the site, now you can see here http://www.bklab.cl/nuevo_sitio/buscar-examenes/
Thank for you help
