Hooks not working and no workaround found

Hello I have a form on a page { https://sarahmarti2.wixsite.com/new-site/new-nanny-registration-form }, I am receiving some information through check boxes. I want to convert value of checked boxes into the text written next to them and store it in database. (Later I want to retrieve these values and show them on a new page in a text box) To do this I am using Hook (insert before). But the hooks are not working. Can you check what is the problem? Are the hooks provided by Wix fully operational at this time? A work around for this was to have a multi select drop down through which people can select multiple values and it can be stored in database. But multi select feature is not available.
Regards
