Hi,
I want to collect participants' date of birth in a form (together with other personal details), and then I want to check what their age is and if it is less than 18, I want to give them some kind of warning message so they notice it (much like HTML 5 does when it highlights the form). The purpose isn't to stop them from continuing, but instead to give them a gentle warning that they have possibly entered their DOB wrong. All the other similar questions were asked more than a few years ago when the custom code worked differently, so please don't point me to these posts as they are outdated to say the least! Thank you! :)
