Hi, I looked at your PayPal Form and checked on this but I didn't come across any issues. It took me to the Paypal Page to collect details necessary to finalize the transaction.
If the problem continues to be reported to you I would advise first clearing your form cache to see if that helps to refresh it for your customers. If not then they may need to clear the browser cache on their end to fix it which should then let them fill in your form and process it into Paypal as normal.
