Error when trying to update named ranges in VBA after modifying Excel data source
I'm working on a project and hit a roadblock. I'm stuck trying to I tried several approaches but none seem to work. I've been struggling with this for a few days now and could really use some help... Recently started working on a client application that involves dynamically updating named ranges in Excel through VBA. The goal is to adjust these ranges whenever new data is appended to the source worksheet. In my current setup, I defined several named ranges, but I'm running into issues when I try to modify them after appending new rows. The error message I get is `Run-time error '1004': Unable to set the RefersTo property of the Name class`. Here’s the relevant snippet where I'm attempting to update the named range: ```vba Sub UpdateNamedRange() Dim newLastRow As Long newLastRow = ThisWorkbook.Sheets("DataSheet").Cells(Rows.Count, "A").End(xlUp).Row On Error Resume Next ThisWorkbook.Names("MyNamedRange").RefersTo = "=DataSheet!A1:A" & newLastRow If Err.Number <> 0 Then MsgBox "Error updating named range: " & Err.Description End If On Error GoTo 0 End Sub ``` The intention is to redefine `MyNamedRange` to include newly added rows. I’ve tried using both direct references and the `Evaluate` method to achieve this, but nothing seems to resolve the issue. Could there be a problem with how the named range is defined, or do I need to ensure the worksheet is active before making these adjustments? Would appreciate any insights or best practices for managing dynamic ranges effectively in VBA. Any ideas what could be causing this? For context: I'm using Vba on Windows. I'd really appreciate any guidance on this. I'm working with Vba in a Docker container on CentOS. Any ideas how to fix this? Thanks for any help you can provide!
