Conflict between datepick and JSON (I think)

Conflict between datepick and JSON (I think)

Hi:

  Page connected to database using JSON. Works fine

    <script src="httpsdocs/js/jquery.loadJSON.js"></script>

 When I tried to add datepick to the date fields the connection to the server is blocked. Nothing in my error logs or DBI->trace.

 I have isolated the problem to <script src=" http://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script> by commenting out the linkages one by one to see when functionality is  restored.

I am very confused on all the jquery release numbers.. This .requires 1.9.1.1 that requires 3.1.1.2 and on and on.

Are the latest releases backward compatible for everything or just a bunch of independent scripts?

Thanks

Robert.
