How to Use Alert Messages responding to A Form Field

[Guest]

Hello,
I am working of a form that has 4 Fields (ID, Lastname, Firstname, Date). I am trying to locate a way to alert the user that the information has been submitted when the "Submit" button has been pressed, and have the form away new input. I am sure that this may be pretty simple, however, I am having trouble trying to locate information. I am using a CFC to process the form - below is the code for this form.
Thanks,
