I get a different error message, which I sent to AC tech.
"Scheduled drugs, per DEA, may not be transmitted or faxed with your current account configuration.
Electronic Prescribing for Controlled Substances (EPCS) is now available nation-wide: contact your EHR for details.
To proceed, uncheck boxes to process scheduled drugs separately."
I'm still waiting for reply.
Did you try to instant chat with them?
