Thanks for the explanation, Wendell. I honestly appreciate it.
It's not my fault that I didn't decline their request because I'm not reading the user board enough. They cold-called me and set a date for the installation. Did they not notice the word Pediatrics in my business name, "Private Pediatrics Inc."?
I genuinely thank you for explaining what has happened. I don't want to spend the hours rolling back to an earlier version with or without their help.
Overall, I remain generally happy with AC, which I have been using since 2006. EPIC has taken over the 2 hospitals of which I'm on the medical staff, and it's a freakin' nightmare. So I don't believe the grass is greener on some other system. But this is the kind of error that is a coding error--something I used to do for a living long ago. The error is understandable, to be expected in this complex work.
But there is no excuse for 1. not informing the client (me) beforehand; and 2. not fixing it pronto once known. It requires no re-formatting, no anything. Just a brief subroutine that looks at the patient's age and how many components there are of the specific vaccine.
Somebody needs to care.
