MSCRM 2011 : Populating Lookup and date field values from Account to Conatct entity

Hi,

My Requirement is

In Account entity

 I have 2 fields

 1. Customer Name (type Lookup) and

2. Date (type Date Only) field

Left navigation of Account entity I had a Contact entity which is having relationship with Account Entity asMany to One (Contact: Account).

In Contact entity I do have a same fieldsCustomer Name and Date fields with the same data type as Account Entity

When I’m trying to open an existing record of contact entity I need to auto populate the Customer Name and Date fields values fromAccount Entity values.

Please let me know how I will resolve this by using the Jscript.

Thanks

Thanks, Toushu
