I'd appreciate it if anyone has tips on how to send different specific responses confirming receipt of a form, depending on either:

1) a check or radio box input

or

2) different Submit buttons

In either case, my goal is the same: send people one of four responses, depending on which one of four options they chose while filling out the form.

Thanks for any advice you can offer!

Have you considered using the PHP Email scripts area for this ?

Thanks for the tip! I'm checking it out and trying to write a basic script to modify responses according to a radio button. I tried this, and it's not initially modifying the message:

$modUserEmailText = $form->UserEmailText;

if($_POST == "Freeze Membership'')
$modUserEmailText .= "Modified message I'm trying to send is here.”;

$userEmail = $modUserEmailText;
$userEmail = str_replace($placeholders, $values, $userEmail);


Also, sorry I wasn't clear in my question, but: While different emails would work, I'd prefer to have different confirmation messages immediately appearing in the browser after you hit Submit, with a different message from each of four options on a single radio button. Is there any script or way to do that?

Thanks again!

Your script is not correct:

should be more like this:

This should provide some insight on how to manipulate submitted information:

If you were not referring to emails, then you can use the PHP Scripts > Scripts called after form process and alter the $thankYouMessage variable:
