Identifying the specific cause of the error is essential to resolve Run-Time Error 1004 effectively. By carefully examining the code, references, permissions, and any conflicting factors, users can pinpoint and address the underlying issue to eliminate the error.

Now that we understand what runtime error 1004 is and its potential causes, let’s explore a few methods to fix this error. Our experts have tested each method mentioned below. Have a look.

Creating Macros

If you are encountering the error while running a macro, check the code for any syntax errors, missing references, or invalid operations. Debug the code by stepping through it line by line, and use error handling techniques to catch and address any potential issues.

Making necessary adjustments to the macro code can often resolve the error. Check how to review macro code and make improvements.

1. Open the Excel workbook that contains the macro you want to review.

2. Press Alt + F11 on your keyboard. This will open the Visual Basic for Applications (VBA) editor.

3. In the VBA editor, locate the project explorer window on the left side of the screen. It typically shows a list of workbook names and modules.

4. Expand the workbook that contains the macro code you want to review by clicking on the plus sign (+) next to its name. This will display the modules within the workbook.

5. Double-click on the module that contains the macro code you want to review. The code editor window will open, displaying the code.

6. Place your cursor at the beginning of the macro code or the specific line where you want to start reviewing.

7. Press the F8 key on your keyboard. This is the shortcut for going through the code line by line.

8. The highlighted line of code will be executed, and the next line to be executed will be highlighted.

9. Continue pressing F8 to step through the code line by line. As you do this, you can observe the values of variables and the flow of the program.

10. If you want to skip over a section of code without checking each line, you can place a breakpoint in the code. To do this, click in the gray margin to the left of the line where you want to set the breakpoint.

A red dot will appear, indicating the breakpoint. When you run the macro, the code execution will pause at the breakpoint, allowing you to review the code from that point.

11. While reviewing the code, pay attention to any error messages that appear in the VBA editor. If you encounter any errors, take note of the line number and the error message. You can use this information to troubleshoot and fix any issues.

Note: By reviewing the macro code in the VBA editor, you can closely examine the logic, variables, and operations performed by the macro. This process helps identify any errors or areas of improvement in the code.
