Creating cascading prompt in Crystal XI

I am wondering if someone could explain to me how to create cascading prompt in crystal here is what I am after.

First Level
• Product (Mandatory)
Second Level
• Order Type (Mandatory)
• Process Type (Mandatory)
• Orderable Item (Mandatory)

The value selected for ‘Product’ will restrict the values available for the subsequent filters

Cheers
