Hi Nursahid A!
I am Shakiru, an independent advisor and a user like you, and I am glad to be helping you out today.
When you delete a sheet that is referenced by a named range in Excel, the named range may become "broken" or "invalid," resulting in the inability to delete it using the usual methods.
To resolve this issue, you can try the following steps:
* Open the Name Manager: Go to the Formulas tab in the Excel ribbon and click on "Name Manager" in the Defined Names group. Alternatively, you can press the shortcut key combination Ctrl+F3 to open the Name Manager.
* Locate the broken named range: In the Name Manager dialog box, scroll through the list of named ranges and find the one that is marked as "invalid" or has a grayed-out "refers to" tab. This is the named range that is referencing the deleted sheet.
* Edit the named range: Select the invalid named range and click on the "Edit" button. The Edit Name dialog box will appear.
* Update the reference: In the Edit Name dialog box, update the reference to a valid range or remove it entirely. You can either change the reference to a range in an existing sheet or delete the reference if it is no longer needed. Click "OK" to save the changes.
* Delete the named range: After editing the named range, go back to the Name Manager dialog box and select the now-edited named range. Click on the "Delete" button to remove it
Kindly let me know, if you require additional assistance, I will be glad to help further.
Best Regards,
Shakiru
