I'm having a terrible time with my forms. If I have multiple items that can be paid for (event registration with optional meal and donations), the form can show the correct amount, but when I land on PayPal, the amount is not always correct. I can then go back to my entry in MachForm panel, and click the payment link, and it IS correct on PayPal.
Has anyone else experienced anything similar? I'm tired of either refunding partial amounts or having to invoice for the remainder. Yuniar has checked my set up and even installed my form on his system and cannot reproduce the problem. My host has whitelisted everything in Mod Security and there's no change. Host support also says there's nothing they can do.
I also have a problem with the IPN, for one form, the "custom" has only 2 parts rather than 3, so Machform IPN rejects it as invalid. SO I'm having to go through each transaction on PayPal to double check payment.
Is there a trace or debug mode that could help identify where this is going so wrong?
Anyone have any ideas?!??
