Hi,
I generated a mart button with multiple price options in Paypal, the pasted the code into the code block in Squarespace.
Testing it on the live web site: The button and all options are visible, and I'm able to get all the way through the payment process with a debit card until the last "pay now" button, which just stalls out and doesn't go anywhere. This is happening to my customers too. HALP!
