I want to connect a aoutoansewre to my form but how?

I'm not quite sure what you meant by "aoutoansewre", are you referring to an autoresponder instead?

If you would like your users to receive an email coming from you after the form is submitted, that can be done by following this guide: http://www.jotform.com/help/26-Creating-a-Form-Autoresponder 

You can also send notifications based on user input, you can do that by referring to this guide: http://www.jotform.com/help/167-How-to-send-to-a-specific-email-address-based-on-a-selection 

I hope that helps.
