How to prevent user to enter a time

Dear Forum,

I have created a form where the user is supposed to enter a start time in one field and a end time in another field.

Then some hidden fields (form calculation widget) will perform a calculation and return hours and minutes in the last field.

How do I use field validation to prevent a user to enter a "End Time" that is earlier than the entered "Start Time" - and how do I make sure that the user enters a "start time" that is not after the "End Time"?

Please see the form in below link.

Any information or help that can contribute to solve this problem, is highly appreciated.

Thank you very much in advance for your great support.

Best Regards,

I'm currently checking your requirements. Please allow me some time to further investigate. I'll get back once I've found results.

You can add a condition to your form that will hide the submit button if the two following conditions are met:

1. End Time is earlier than the Start Time

2. Start Time is after End Time

Let us know if you need further assistance.
