Here i have included my codings for the date picker calendar
while running this calendar in mozilla there is no error but the
calendar is not displaying i think there is a problem in the line
156(crossobj = (document.getElementsByName)
? document.getElementsByName("calendar") : null plz try to rectify the
problem any one. Also please provide the correct coding to run in
mozilla.

Thx in advance
