Delete pages before emailling

I have a four page form; pages 2-4 become visible when a dollar amount reaches a certain value. The form also has a button that emails the form to approvers. Is it possible to actually delete pages 2-4 if the dollar amount does not reach the value?

Or is it possible to only email the first page?

email is using

try {

myDoc.mailDoc({

    bUI:true,

    cTo: email ,

    cSubject: sbj,

    cMsg: Msg,

    cSubmitAs: "PDF"
