Thank you for your post.
Using the bps_Contacts table, create a new blank layout. On the layout, type your letter and enter:
<<First Name>> <<Last Name>> to enter the first and last name fields. That is whenever you want to insert a field into the text portion, enclose the field within << and >>.
Go to Browse mode, and you should see the letter with the appropriate field information embedded in the parts of the letter.
