I am trying to send invoices, but once I enter all of the required information (item description, qty, price, etc.) and hit Preview or Send, I get an error that says "Some of the fields have invalid values. Please correct and try again." However, none of the fields appear to have invalid values. I have started a chat with Support, but so far they just keep telling me the instructions for creating an invoice. I KNOW what the instructions say, and I'm following those instructions, but still getting the error message. Anyone else had this issue or have any ideas for me?
