Hi,custom weblink to create new activity record does not populate Start Date and End Date fields of

Hi,

In Event module there is a custom weblink "Add to Calendar". We are using this weblink to create new activity record and passing some values from event module like Event Start Date, Event End Date, City/Town etc, as follows.

https://secure.crmondemand.com/OnDemand/user/DefApptNew?OMTGT=ApptEditForm&OMTHD=ActivityNewNav&OMRET0=Calendar%3fcal%3d0&ApptEditForm.Type=Event&OCTYPE=Event&ApptEditForm.Description=%%%Name%%%&ApptEditForm.ZText_31=%%%Row_Id%%%&ApptEditForm.Status=In Progress&ApptEditForm.Planned=%%%Start_Date%%%&ApptEditForm.Planned+Completion=%%%End_Date%%%&ApptEditForm.ZText_0=%%%Name%%%&ApptEditForm.MeetingLocation=%%%stCityTown%%%&ApptEditForm.ME+Event+Id=%%%Row_Id%%%&ApptEditForm.Category=General

But issue is when user clicks on this "Add to Calendar" weblink Start date and end date in the activity record remains null .
