Hi, I am receiving this error every time I try to tick an invoice to receive a payment against in the Rec Payments window. The only work around is for me to manually enter the amount of the invoice in the 'amount' section. I can no longer just tick the invoice or this msg pops up. There is no amount that I am applying so I do not understand why its popping up, I am just trying to tick the invoice. This has been happening for a couple of weeks now. Any ideas? @Rav
