How to Fix VBA Error 1004 with the Intersect Method in Excel
Question details
The user is encountering VBA Run-time Error 1004 when calling the Intersect method in a Worksheet_Change event.
- Product
- Excel / WPS Spreadsheet
- Device & OS
- not provided
- Scenario
- Writing or running a VBA macro that utilizes a Worksheet_Change event to monitor modifications within a specific named range.
- Observed behavior
- Run-time Error 1004 is triggered when the Intersect method evaluates an active cell that happens to be outside the monitored range, due to using 'ActiveCell' instead of the event's 'Target' parameter.
Before modifying your worksheet's VBA code, ensure you stop any currently running macros and save a backup copy of your workbook.
Replace ActiveCell with the Target Parameter
Using the Target parameter ensures your code only evaluates the specific cell that was actually modified, avoiding out-of-bounds errors caused by referring to an unrelated active cell.
The Worksheet_Change event automatically passes a 'Target' range object representing the exact cells that triggered the event. When 'ActiveCell' is used inside the Intersect method, VBA may throw Error 1004 if the selection has already moved to a cell outside the expected evaluation scope (for instance, pressing Enter moves the active cell down). By referencing 'Target', the code reliably evaluates the exact range modified without throwing errors.
Press ALT + F11 on your keyboard to launch the Visual Basic for Applications (VBA) editor.
In the Project Explorer pane, double-click the specific Sheet module where your Worksheet_Change event code is located.
Find the line of code causing the error, which likely looks similar to: 'If Not Intersect(ActiveCell, Range("rangeMonths")) Is Nothing Then'.
Change the word 'ActiveCell' to 'Target' so the statement reads: 'If Not Intersect(Target, Range("rangeMonths")) Is Nothing Then'.
Save your VBA project, return to the worksheet, and edit a cell to confirm that Error 1004 no longer appears.

Frequently Asked Questions
What does VBA Error 1004 mean?
Run-time error 1004 is a generic 'Application-defined or object-defined' error in VBA. In the context of the Intersect method, it typically means the ranges being compared are invalid, are located on different worksheets, or reference an inappropriate object.
Why does ActiveCell cause an error in a Worksheet_Change event?
When a user edits a cell and presses Enter, the selection cursor often moves to the next adjacent cell. The 'ActiveCell' then becomes the new cell, not the one that was just changed. If this new cell falls outside the macro's expected evaluation scope, evaluating it via the Intersect method may result in an error.
Can I use the Intersect method across different worksheets?
No, the Intersect method only works when all the referenced ranges are located on the exact same worksheet. Attempting to intersect ranges from two different sheets will trigger a run-time error.
How do I check if the Intersect method returns nothing?
You check the result using the 'Is Nothing' condition in an If statement. For example, 'If Intersect(Target, Range("A1:A10")) Is Nothing Then' means the modified cell does not overlap with the specified range of A1:A10.
