Notes/Domino 4 and 5 Forum

I'd like to add a prompt to a button that verifies the user is the true submitter. The button will list document titles and ask user to verify if he/she will comply with the document. How do I prompt and test for the user's Notes pw?

AllDocs := ("Doc 1": "Doc 2" : "Doc 3");

Doc:=@Prompt([OkCancelList] : [NoSort]; "Choose a Document..."; "";"On which Document would you like to send verification?"; AllDocs);

@MailSend( Sendee ;"" ; "" ; "Document Verification for " + Doc ; "" ; @Name([CN];@UserName) + " is verifying he/she read, understands and shall comply with " + Doc);

@Command([FileCloseWindow])
