Send filled pdf in email

How can I attach the filled PDF from my form when it is submitted to email out? ive used [default-message][e2pdf-attachment id="[id]"] in the email section. If i specify the ID i can send a specific form, and it works fine, but i need it to pull the ID of the entry and send that, so it always emails the one that was just submitted automatically.

nevermind i got it
