Suppose you have Datefrom in your main form and you want to call calendar function. Please call this function from On Click event

 

 x1=event.x; y1=event.y; calendar("Datefrom",x1,y1)

Put the following code in On Load event on the Main Form

 document.all.redbox.style.visibility="hidden";

Please choose Generate HTML for all fields in the Main form.
