Hi there,
I just installed Form Builder today and I can answer your question
Click on your Form Name in the Form Builder edit area.
Click the TAB called FORM SUBMISSION, just to the right of the Tab called MAIN.
You will see:
Form Submission Behavior
After form is submitted: [select one of the following]
Display "Submission Template"
-- or --
Redirect to site page
If you select the second option "Redirect to site page", you need to specify WHICH page:
Page to redirect to after form submission: [select page from popup]
If you don't choose a page or a redirect, the form returns to INDEX.HTML in the browser URL line, but you can also have a message appear on the screen.
To do so, select the Tab, SUBMISSION TEMPLATE, click the button to add the HTML, and then type your message at the top. Delete any html you don't need.
Just in case you didn't find it yet, here's a page all about Form Builder. I'm just reading now to see how to get MY form to work
Good luck!
