Hi. I'm trying to use a lightbox to act as an entry checkpoint for my site. Essentially, I have a field in a database called 'App' and I want a visitor to my site to be greeted by a lightbox that prompts him to enter a verification number. The verification number should validate existence of the value against the 'App' field and if found, close the lightbox and allow access. If not found, it should display an error 'Invalid code.'
Complete noob for Wix - so any help would be appreciated.
Thanks in advance!
