Fix Excel VBA Worksheet Change Macro Does Nothing

Question details

An Excel VBA Worksheet_Change macro fails to execute its intended function (placing values in column B based on changes in column A) because a range variable was declared but never assigned.

Product: Microsoft Excel
Device & OS: not provided
Scenario: Automating cell updates across columns using a Worksheet_Change event in VBA.
Observed behavior: The macro triggers without producing any errors, but no values appear in column B because the unassigned range variable causes the logic to be bypassed or fail silently.

Before you start

Verify that your macro security settings in Excel are set to allow VBA code execution, and ensure your code is placed inside the specific Worksheet module rather than a standard module.

Solution 1Recommended

Assign the Range Variable Using the 'Set' Keyword

Properly assign the target range variable before evaluating it with Intersect or running loops to ensure the VBA event triggers correctly.

In VBA, object variables like Ranges or Worksheets must be assigned using the 'Set' statement. If you declare a range variable but forget to assign it, checking it with Intersect(Target, rng) will evaluate to Nothing, causing your macro logic to skip entirely.

Open the VBA Editor

Press Alt + F11 to open the Visual Basic for Applications editor, and double-click the specific Worksheet module where your code is located from the Project Explorer.

Locate the Worksheet_Change Event

Find the 'Private Sub Worksheet_Change(ByVal Target As Range)' procedure that is failing to execute.

Add the Set Statement

Right before your Intersect check or For Each loop, explicitly assign the range variable. For example, insert the line: Set rng = Me.Range("A2:A12").

Test the Macro

Save your VBA code, return to your Excel worksheet, and make a change within the A2:A12 range to verify that column B updates successfully.

Syntax Reminder: Always remember that simple data types (like Integer or String) use the standard '=' operator for assignment, while Object types (like Range or Worksheet) require the 'Set' keyword.

Frequently Asked Questions

Why does my Worksheet_Change macro loop indefinitely?

If your macro modifies cells within the worksheet, it triggers another Worksheet_Change event, causing an infinite loop. You can prevent this by wrapping your cell modification code with 'Application.EnableEvents = False' and resetting it to 'True' when done.

Where should I place Worksheet_Change VBA code?

Worksheet_Change code must be placed inside the specific Worksheet object module (e.g., Sheet1) in the VBA editor. If it is placed in a standard module (e.g., Module1) or ThisWorkbook, it will not function correctly.

How do I check if a specific cell was changed in VBA?

Use the Intersect method with the Target parameter provided by the event. For example, 'If Not Intersect(Target, Range("A1:A10")) Is Nothing Then' checks if the modified cell falls within the A1:A10 range.
