hello to everyone, it’s just what I was looking for. However I do not know exactly where to enter the code. I do not know if the first code suggested by Jonathan is to be inserted (if it is linked in some way to the second or less), in case I do not know where. I do not even know where to put the second piece of code suggested by yarongo.
I tried to integrate a js as suggested by this procedure, http://www.advancedcustomfields.com/resources/adding-custom-javascript-fields/
The code is in the page source but it does not work.
The parameters #firstdate, #seconddate have been changed to those set by me.
I use datapickers inside a repeating field. Thank you so much for any response.
