Can I create an approval process with my form?

Like when a form is submitted it is submitted for approval. If it gets approved it is sent to the appropriate people. If declined it gets sent back the the person who submitetd it.

If I understood your question correctly you are referring to an approval workflow. If this is the case, you can check the steps provided by my colleague here: http://www.jotform.com/answers/401633#401648  to see how can this be done.

Hope this will help. Let us know if you need further assistance.
