I've been stuck on the AMOUNT_ERROR message when processing PayPal payments. Our website that's been up and running for a while. The same code works with the SANDBOX url but not with the PRODUCTION url. We have been loosing money for days trying to figure this out. As of May 30, 2018 (10am) it stopped processing and only gives the "Things don't appear to be working at the moment" message. And the URL says: https://www.paypal.com/webapps/shoppingcart/error?flowlogging_id=54a5c550d73a1&code=AMOUNT_ERROR&mfi...I double checked my amount values to make sure we weren't using any commas and trimmed it to make sure there were no blank spaces in the variables. My form values are below, any help that anyone can provide would be greatly appreciated. (p.s. HTTPS Secure Connection Test: I also replaced the Production URL with the tlstest.paypal.com/cgi-bin/webscr in the action tag to make sure I got an "connection ok" message for the TLS 1.2\HTTP 1.1 protocols):
