The object can be a workbook, worksheet, range, variable, class, macro, etc. Some users have also reported that this error occurred when they tried to copy the values of the cells from one workbook to another.
Let’s understand the error through a small scenario. Suppose, I want to check the last field row in a table in a spreadsheet named “First” using the VBA code. To do this, I have added a command button and double-clicked on it and entered the below code in the backend:
Private Sub CommandButton2_Click()
Dim LRow As Integer
LRow = Worksheets("First").Cells(Rows.Count, 2).End(xlUp).Row
MsgBox ("Last Row " & LRow)
End Sub
In this code, Worksheets("First") is a data object. If I mistakenly delete this data object and insert any random name (for example - kanada), then it will not be recognized by Excel. When I run this code, I will get the “Run-time error 424”.
