I have a membership form that submits payments to PayPal. I have been receiving payments successfully. One user, however, is getting the error “Error! Invalid payment amount!” His “Total Due” amount is higher than most others, due to his form selections. But the amount looks correct and reasonable. I have updated everything, including Forminator, to the latest version but the user is still getting this error. How can I troubleshoot and solve this?
Total Due is a calculated field. It has been working for several years. Here is the calculation:
round((Annual Dues+Additional Fees+Additional Donation)*(Payment Processing Fee+1)*100)/100
