Registration page (form builder) with multiple redirects

[waldus68]

My client would like to have an event registration form, after submission the customer is redirected to a paypal payment button. Form builder is working great for this; however they would now like to include an early submission option, which includes a discount.

Is it possible to include a drop down or other selection method in Form Builder that would redirect the user to another page after submission (with the appropriate paypal button) based on a selection?

They (the client) are alright with trusting the user to select the correct one (and they will verify it) but they would rather have this, than multiple buttons.

Thanks,
Dustin
