Hi,
Can you show me, how to validate an age after we click datetime box.
or might be there already custom function create for this case

for example,
By creating form and using datetime box,
System only allow user who have age more than 18, to register on my website.

can you give me a hand..

thanks🙂

Hi ajinugrohu,

Ther's nothing built in to ChronoForms to do this but you can find some scripts with Google. Here's one example.
