Question details

The user needs to resolve an Excel VBA run-time error 9 and a dynamic range selection error that occur while transferring data from a protected template.

How to Fix Excel VBA Run-Time Error 9 and Data Transfer Issues

Product: Microsoft Excel
Device & OS: not provided
Scenario: Automating data transfer from a protected template sheet using an Excel VBA macro.
Observed behavior: The macro throws 'Run-time error 9: Subscript out of range' due to an incorrect worksheet string reference, and data transfers fail when the last used value isn't in the expected column.

Before you start

Before modifying your VBA script, ensure you have saved a backup copy of your macro-enabled workbook (.xlsm) and unlock any protected sheets temporarily to accurately test the data transfer logic.

Solution 1Recommended

Correct the Worksheet Count Syntax to Fix Error 9

Resolve the 'Subscript out of range' error by removing quotation marks from the Worksheets.Count property to correctly reference the sheet index.

Run-time error 9 typically occurs when VBA attempts to reference an object that does not exist. By enclosing 'worksheets.count' in quotation marks, the macro searches for a literal string name rather than computing the numeric count of the worksheets.

Open the VBA Editor

Press Alt + F11 on your keyboard to launch the Microsoft Visual Basic for Applications editor.

Locate the problematic module

In the Project Explorer pane on the left, double-click the module containing your data transfer macro.

Find the incorrect string reference

Locate the line of code that reads: Set sourceSheet = ThisWorkbook.Worksheets("worksheets.count").

Update the syntax

Replace that line with: Set sourceSheet = ThisWorkbook.Worksheets(Worksheets.Count). This correctly passes the integer value of the last sheet's position instead of a string.

Correct the Worksheet Count Syntax to Fix Error 9

Verify Worksheet Positions: Using the Worksheets.Count property reliably targets the very last sheet in your workbook, regardless of its assigned name.

Solution 2

Calculate the Last Used Row and Column Independently

Prevent dynamic range data transfer errors by independently calculating the last used boundaries of your source data.

Frequently Asked Questions

What does 'Run-time error 9: Subscript out of range' mean in VBA?

This error occurs when your VBA code attempts to access a collection member (like a worksheet, array index, or workbook) that does not exist. It often happens due to misspelled sheet names, missing files, or referencing an index number that exceeds the total count.

Why does my dynamic range selection fail when transferring data?

Dynamic ranges fail when the script wrongly assumes a specific column or row will always contain the last piece of data. If the actual last value is in a different column (e.g., not in column N), using methods like .End(xlToLeft) on the wrong row might return an unexpected boundary, causing the range to be invalid.

How do I correctly find the last used row and column in VBA?

You should calculate them independently using the .End method. For the last row, use Cells(Rows.Count, 1).End(xlUp).Row. For the last column, use Cells(1, Columns.Count).End(xlToLeft).Column. Then, combine them into a Range or Cells property to securely define your target area.
