How to Troubleshoot Excel VBA Macros Skipping Procedures and Errors
Question details
The user needs to troubleshoot a VBA macro that skips procedures, generates clipboard errors, opens unexpected windows, and prevents row grouping on a specific worksheet.
- Product
- Excel
- Device & OS
- not provided
- Scenario
- Running a main VBA macro that calls multiple sub-procedures to process data and format a worksheet.
- Observed behavior
- One procedure is skipped without throwing an error, multiple unexpected application windows open, a clipboard error occurs, and row grouping fails on the Total worksheet.
Before modifying your VBA code, save a backup copy of your macro-enabled workbook (.xlsm) to ensure you can revert to the original script if needed.
Reveal Hidden Errors and Verify Procedure Calls
Disable error-hiding statements to identify the exact line causing the macro to fail or skip procedures.
Often, VBA code utilizes 'On Error Resume Next' to bypass expected issues. However, if left globally active, it can mask critical errors that cause sub-procedures to be skipped entirely.
Press ALT + F11 to open the Visual Basic for Applications Editor and locate your main macro module.
Comment out or temporarily delete any 'On Error Resume Next' statements in your code. Run the macro again so the compiler can highlight the hidden error.
Ensure you are using the correct syntax to trigger sub-procedures, such as 'Call MySubRoutine'. Additionally, verify that no stray 'Exit Sub' commands or unexpected 'If' logic are prematurely ending the execution.
Resolve Clipboard Errors and Unexpected Application Windows
Manage external automation commands and clear the clipboard to stop unexpected windows from appearing.
Restore Row Grouping on the Worksheet
Adjust sheet protection and outline settings to ensure row grouping works correctly on your Total worksheet.

Frequently Asked Questions
Why is my VBA macro skipping a subroutine without giving an error?
This usually happens if you have an 'On Error Resume Next' statement active, which tells Excel to ignore errors and proceed to the next line. It can also occur if the subroutine call is bypassed by an 'If' condition or an 'Exit Sub' statement.
How do I fix clipboard-related run-time errors in VBA?
Clipboard errors often occur when the clipboard is locked or overloaded by repeated copy-paste operations. To fix this, insert the command 'Application.CutCopyMode = False' into your code immediately after your paste operations to clear the memory.
Why won't my rows group or outline on a specific worksheet using VBA?
Row grouping will fail if the worksheet is protected. Ensure your VBA code unprotects the sheet before applying the grouping. Additionally, you should use 'ActiveSheet.DisplayOutline = True' to ensure the outline symbols (+/-) are visible to the user.
