How to include body text on reply using hotspot button

I have below as formula in a button.I have figured out how to get the subject included in the automated email but nhot the body of the original mail.

Can anyone help?

choicelist:=" Accepted":" Declined";

email:="james.beresford-wylie@amcor.com":"ann.ruddock@amcor.com";

message:=“Please select your choice from the list below:”;

choice :=@Prompt([OkCancelList]:[NoSort];title;message;“”;choicelist);

@MailSend(email;“”;“”;@Name([Abbreviate];@UserName + " has_ " + choice + ( Subject) ));

@Prompt([Ok];“Finished”;“Thank you, your response has been emailed to Amcor.”)

Subject: look in help db

Lookup @MailSend in designer help. There is a parameter at the end where you can include fields on the document, use [Body]
