Quote Error message: Service bad request error: Could not complete request, input was malformed. (status code 400)

I keep getting this error message "Service bad request error: Could not complete request, input was malformed. (status code 400)" and can't send a quote. Is there a way to fix this?

Hi Fran, I've got some follow-up questions that would make this a better conversation to have with a support ticket.  I'll be sending you an email to follow up further.
