I have to create launch page wherein depending on the selection of radi buttons i have to change the calender begin date and end date. how to hold those variables in javascript and how do i pass them in the calender. Please help me with it.
Currently i m holding the start and end variables in as
var BEG_D = "!IBI.AMP.BEG_D1;"
var END_D = "!IBI.AMP.END_D1;"

is that a correct method to hold a variable in javascript?
if yes how do we pass it to the calender field?

If you already have the values you need in JavaScript variables, you could assign them to any element in your HTML document using JavaScript as well:

document.getElementByID('calendar1').value = BEG_D;
document.getElementByID('calendar2').value = END_D;

Do you store the dates for each radio button ?

You may have to do more js coding to set for each radio button.

i have created a XML file for calender! the calender code first checks for the value of radio button and then goes to that part of calender accordingly! But i dont know how to include that XMl file in html! Can someone help me with it!
