I solved with the help of Marcos Brinner, the problem that was with DetePicker as #
But he painted another question about the asynchronous request, between DetePicker (Timetable) and Schedules.
I thought that following the reasoning of the other previous requests, I could bring the schedules of individual attention of each professional, by selecting the desired date and available in their calendar. But to no avail.
With the help of friends to understand why, I'm posting a temporary address so friends can see what's happening (or rather, what's not happening).
At the address, friends will be able to Download the used files as well as the images of the Calendar and Schedules tables.
Thanks in advance to everyone for the attention to my problem.
