Fixing Mumps Error: Missing Global Variable In CareVue Labs Tab.pdf

## Fix Mumps Error Received on CareVue Labs Tab for Micro Results

This error occurs when trying to view a patient’s micro result in CareVue due to the absence of a critical global variable ("zero node") associated with the accession number.

Possible Causes:

Timed Out Session: A user's session may have timed out, disrupting the data access.
Data Entry Error: An error during specimen accessioning could have led to incomplete data.
* System Glitch: A problem within the system itself could have caused the zero node to be missing.

Troubleshooting Steps:

1. Access Programmer Prompt: Open the programmer prompt and execute the command `D ^%G` to display all global variables.
2. Locate Missing Node: Identify the accession number (e.g., "MI 13 13095") causing the error by examining the output. Note the missing zero node in the global list.

3. Access Microbiology Menu: Navigate through the Lab DHCP menu to access the Microbiology menu and select "Results entry" for the specific accession number.
4. Verify Data Entry: Double-check the data entered for the specimen, ensuring accuracy and completeness.
5. Recreate Zero Node (if necessary): If data entry appears correct but the zero node remains missing, a system administrator may need to recreate it through the programmer prompt.
6. Print Global List: After resolving any issues, print the global list again to confirm that the zero node has been created successfully and the error no longer appears in CareVue.
