Hi
I have been using Express Invoice v 3.90 for a week or so. A couple of times I have gone into my invoice list to add a payment and I get the following message "Customer not found. Please create the customer entry before proceeding with payments." I don't understand why I am getting this message as I have created the invoice, recorded and emailed it to the customer, and it is there with all the others in my invoice list.
If I try to go into it another way, by going directly to "Apply payment" from the main screen, rather than through my invoice list, I can find the customer but the outstanding amount is showing as zero and the invoice details are not there, just the customer name.
What am I doing wrong please? Most of the invoices seem to be fine, just the odd one or two. Thank you!
