OK, thank you very much
The problem is that I can’t keep track of all of a patient’s procedures.
and this is my recovery code

You need to be a lot more specific here. Please describe in detail what you’re expecting to have happen, and what’s actually happening. If you’re getting a traceback, please post the complete traceback. If not, describe the results you are getting.
