How to get alert when departure date is earlier than arrival date

I want to add a condition with the date pop-op funtion.

When someone enters a value af the departure date, that is earlier than the Arrival date, I want them to let them know that the dparture date has to be later than the arrival date?

How can I get this alert?

Hi,

When you say alert, you mean to say a warning message?

How about using check-in check-out widget where users can't pick dates later than the check in date? You can get it here: http://widgets.jotform.com/widget/check_in_check_out

However, if you want to use the default DateTime fields, you can achieve that with condition.

1. First, get the calculation of the two dates. Formula is departure - arrival

2. Create a condition that if the result is negative (meaning departure is earlier than arrival), show a warning message. You can compose a warning message using Text tool under Form Tools.

3. Otherwise if the result is negative, no warning message will appear.

Example: http://form.jotformpro.com/form/50604250839958?

Clone this form so you can figure out how I setup these fields and the single condition.

 If you need further help, let us know.

Regards!

This gives me a lot of trust!

I am going to give it a try!!
