Not really but, without an example, there's no way to help. If you don't mind sharing a link to the page that has the code, perhaps you could get some help. There's been some changes as to the variable values accepted and some variables are not valid any more. For example, the "amount" variable value will fail if there is a currency symbol included with the amount - meaning, if $5.00 is entered or sent to the PayPal Checkout Screens, it will fail and you will get an error message - the correct accetable value would be 5.00. Note, you cannot include a comma either as $3,000.00 would fail but, 3000.00 would be fine. There has been a few other changes, so we really need to see the button code.
