I am using OD 19.4. I tried to add a treatment plan after first creating an auto code for immediate denture.
I select Entry Status: TreatPlan, Procedure button Prosthodontics, but when I click on the immediate denture quick button, i get a message:
"Critical Error: Object Reference not set to an instance of an object"

What could be an issue?
Please help.

In 19.4.45, i tried creating a quick button with a similar auto code attached to it, but I was unable to produce an error when clicking it on the chart module. If you are not on version 19.4.45, I would try getting the most recent updates for 19.4 and see if the error persists. If it does, and the error has a stack trace or other additional text, please post it here. Providing the specific details of the auto code and quick button configurations may also help us trouble shoot this.
