I'm not sure, that title is correct, but i'll try to describe my qyestion in more detail. 
What i have?
In Lotus db i have view V1 with two columns - names and address. Also i have two forms (for simplicity - F1 and F2). F1 has two fields: "Recipient" (names) and Title (text string) and Button "Send". F2 also has field Title (text string). After opening DB person can choose one document from view V1 and press button "Create", which creates new document on F1, where field Recipient takes chosen address from view V1. Then person fills field Title and press button "Send" to send message for Recipient with doc.Subject = Title . On this stage everything is clearly understandable

What i need?
In this mail, Recipient should receive link for creating new document on form F2, with automatic filling for the field "Title" with the "Subject" value from this mail.
