PayPal unable to validate return URL?

[ArtyHelen]

In the payments section of my shop, for paypal.com, it suggests I set my return URL at PayPal to
http://www.shopartyhelen.com/shop/in...eckout_process

But when I do this, PayPal tells me "We were unable to validate the URL you have entered. Please check your entry and try again."

Would it be OK if I just set the return URL to http://www.shopartyhelen.com , or is there some way I can force it to accept the right one?

Thanx!

Helen

it will be OK to just leave it as domain name.
