A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
sounds like you are putting it in the wrong place.
do the Alt+F11. In the project explorer on the left, find your workbook/project. You should see ThisWorkbook under modules. Right click on that and select view code.
Paste you code in that module.
It is the module used to house workbook level events. the Workbook_Open event is a workbook level event.
When the module first appears, it may already be populated with a workbook_Open event skeleton. You can delete that and then paste in your code.
The option explict must appear at the top of the module.
now delete the same code in the module you inserted. Save the workbook.
Code in the workbook_open event should run everytime the workbook is opened and code is not disabled.
