Hi,
You have to write script in js widget and set that in html widget for display.
// script to get data and set data
var html_values = " " ;
// get values from widget
var name = RMPApplication.get("name"); // name is value variable of Name widget
var date =RMPApplication.get("s_date"); // s_date is string variable of date widget
html_values = "Hello " + name + "<br>" + "Today's Date - " + date;
id_html.setHtml(html_values); // id_html is identifier of html widget.
Note : "String date variable" will return date according to "Pattern" field. And "numeric date variable" for a "Date input" will return the number of seconds since 01/01/1970.
Hope this helps you.
