How can I redirect customers to a custom 'thank you' page, using a PayPal Smart Button?

[tracey81]

Hi there,

We have set up a PayPal Smart button on our website.

We've also created a custom thank you page on our website too.

And now we want customers to be redirected to that custom thank you page, upon successful payment.

We have turned on the set the 'Auto return for website payments' and added a custom URL here:

PayPal Login > Account Settings > Products & Services (Website payments) > Website Preferences > 'Auto return for website payments'

...but it doesn't work.

Please help!
