What are you trying to accomplish with the form? The form is set to post to the same page that the form is on. If you want to upload the information to a database, DataAssist is helpful in accomplishing this. If you want to email it to someone, Universal email will help with this. Form builder is used for designing and building the form, it will not handle what happens after the form is submitted.
