Hi. I have a site where request a booking for a specific period. The request is written to a database using a custom form. In the form there are two date pickers for the "arrival-date" and the "departure-date". I want to make a check that the "departure-date" is at least one past the arrival date. I tried to use code for this, but never used it before so in the end I could not work out how to do this. Does anybody already have a similar check build on their site and can show me what the code looks like?
