How to use Opty Revenue fields in Contract Table template?

Hi,

I've downloaded the ECMTableVarFileSub.rtf to make some changes. In this file, we have the table called ChildRevenueTableTemplate.

• How can I use this table in my Contract Terms Template if there is no variable associated to that?
• I created a new variable for Opportunity Child Revenues, using the same table template name, but didn't work, it doesn't show any information on the output pdf.
• Also, how can I add custom fields to this table?
