I checked your form and I can see that you have already setup a redirect link.
I would like to inform you that the user will need to manually click the "Return to merchant" button after they make the payment so they will be redirected to the Vcita page you have set. Unfortunately, it is not possible to redirect to the site without clicking on the link.
Alternatively, you can enable the auto-return on your paypal account and enter the vcita url in the return url. Here's a guide that may help: Auto Return Overview.
