Submission receipts would work for this scenario. However, they only work with an email address text field and not a drop down list. The student would have to type in the advisor's e-mail address - you could provide a list of them on the form itself to make it easier.
I explained how submission receipts work in this post: http://forums.adobe.com/thread/918711
I would also like to have additional options for submission receipts. In my situation, a person is identifying themselves via a dropdown menu list. As it stands they have to add their email address separately, but it would be nice if an email address could be associated with an entry in the dropdown menu. In addition, it would be nice if the person's supervisor also received a copy of the submission. That doesn't seem to be possible currently, but ideally it would be nice if it was also associated with the initial dropdown menu. In that case, the person would pick their name from the list and then submission receipts would be send to the submitter and their boss automatically.
I'm also interested in defining a list of email addresses on the form itself (preferably in a drop-down menu with an "other" option), rather than asking users to type in their email address each time. My forms serve a team that's pretty static, and considering that they will be using it frequently, typing out their addresses each time can be tiresome.
An email notification that works off a dropdown selection would be a great feature. Right now I'm trying to create a booking form for seven different locations, and I want an email to be sent only to the email of the location that is selected by the customer. The only way I can make this work (without manually typing in the email - which isn't feasible with customers) is to duplicate the form seven times and set the notification email for each form to a each location.
