How to set date picker to tomorrow's date

Name the date & time prompt as "FromDate".
Add in a HTML item (after the prompt).
In the HTML item, write the definition like this: (replace $$ with triangle brackets )

$$script$$

function addDay ()
{
var dtToday = new Date();
var dtTomorrow = new Date( dtToday.valueOf() + 86400000 );
// NOTE 86400000 = 24 hours * 60 (minutes per hour) * 60 (seconds per minute) *
// 1000 (milliseconds per second)
var strTomorrow = [dtTomorrow.getUTCFullYear(), dtTomorrow.getMonth()+1, dtTomorrow.getDate()].join("-");
return strTomorrow ;
}

function ReturnTime ()
{var Time = "00:00:00.000"; return Time;}

pickerControlFromDate.setValue( addDay() );
timePickerFromDate.setValue( ReturnTime() );
