How to Fix "Ambiguous Name Detected" Error in Word VBA
Question details
The user is encountering an "Ambiguous name detected" compile error in Word VBA because multiple event procedures have been created for different content controls.
- Product
- Word
- Device & OS
- not provided
- Scenario
- Attempting to run separate VBA logic for multiple content controls (such as Rating, Risk, and Score) using the Document_ContentControlOnExit event.
- Observed behavior
- VBA throws an "Ambiguous name detected" error because there are duplicate procedure names within the ThisDocument module, preventing the macro from compiling and running.
Open your VBA editor and identify the module throwing the error, ensuring you save a backup of your current macro code in a simple text file before making structural changes.
Combine Multiple Event Procedures into One Handler
Since Word only permits a single Document_ContentControlOnExit subroutine per document, you must merge all your control-specific logic into one procedure using conditional statements.
The "Ambiguous name detected" error occurs when the VBA compiler finds multiple procedures with the exact same name in the same module. In Word, predefined event handlers like Document_ContentControlOnExit can only be declared once in the ThisDocument module.
To run different code for different content controls upon exit, you need to use a single event handler and route the logic using the Title or Tag property of the ContentControl object.
Press ALT + F11 on your keyboard to open the Visual Basic for Applications (VBA) Editor. In the Project Explorer pane on the left, double-click 'ThisDocument' to open the code window.
Scroll through your code to find all instances of 'Private Sub Document_ContentControlOnExit(ByVal ContentControl As ContentControl, Cancel As Boolean)'. You will likely see multiple subroutines with this exact name.
Keep only the very first 'Private Sub Document_ContentControlOnExit' declaration and its corresponding 'End Sub'. Delete the duplicate 'Private Sub' and 'End Sub' lines, keeping the inner logic blocks intact.
Inside your single subroutine, type 'Select Case ContentControl.Title' to start a conditional block. Below it, create cases for each control, such as 'Case "Rating"', 'Case "Risk"', and 'Case "Score"'.
Cut and paste the specific code for the Rating control under 'Case "Rating"', and do the same for the others. Finish the block by typing 'End Select' right before 'End Sub'. Click Debug > Compile Project to ensure the ambiguous name error is resolved.
Edit and Run VBA Macros Seamlessly in WPS Writer
WPS Office provides robust VBA support, allowing you to edit, debug, and run macros just like in Microsoft Word. Fix ambiguous name errors and manage your content control events efficiently using the built-in WPS Macro Editor.
- 1. Open the Document: Launch WPS Writer and open your macro-enabled document (.docm).
- 2. Access the Macro Editor: Navigate to the 'Tools' tab on the top ribbon, click on 'Macros', and select 'Macros Editor' (or simply press ALT + F11).
- 3. Modify the Code: In the left Project Explorer panel, double-click 'ThisDocument'. Locate the duplicate Document_ContentControlOnExit procedures and merge them using Select Case logic.
- 4. Save and Test: Click the Save icon in the Macro Editor, then return to your WPS Writer document to test the content controls without errors.
Frequently Asked Questions
What does "Ambiguous name detected" mean in VBA?
This compile error triggers when the Visual Basic Editor encounters two or more procedures, variables, or constants that share the exact same name within the same module or scope level. Removing or renaming the duplicates resolves the issue.
Can I have multiple events for different content controls?
No, you cannot declare multiple Document_ContentControlOnExit subroutines in Word VBA. You must use a single event subroutine and apply conditional logic, such as an If statement or Select Case, targeting the ContentControl.Title or ContentControl.Tag to handle the actions for different controls.
How do I access the VBA Editor to fix this error?
You can open the Visual Basic for Applications (VBA) editor by pressing the ALT + F11 keyboard shortcut while your Word document is open. From there, navigate to the module where the error is highlighted to make your corrections.
