Date Time Validation
I need some help with the Date/Time validation.
I want to check the age, via, 3 select boxes.
I use this validation yyyy-mm-dd
I think the problem are the select boxes. Cause if I use a simple input field, it works well.
To fix I tried to create the month and day value with date "n & j" but I think this does not work with the yyyy-mm-dd
