Interactive pdf forms

1. Hi, I have created an interactive form. Have created a submit button so i can email the form back once completed but this pops up "invalid file specification object' - how to create this and/or fix this?

2. Is there anyway I can save more than one signature on the tablet? so it saves time to drop the specified signature rather than sign and resize every time?

3. Is there a cc field i can include when emailing the form back?
