Object defined error while looping through worksheets - vba

Question

I have a project I am working on that entails looping through a series of worksheets, each of which is named after a series of values in a separate sheet. I then perform some functions on each sheet, adding a formula to the next empty column. However, my code is erroring out at this line:
Worksheets(Name).Range(.Cells(2, LastColumn + 1)).Formula = "=F2"
The specific error is
"Application-defined or Object-defined error"
and I'm not sure why this is occurring. I've switched up the way I reference the worksheets, moving around the With-blocks etc. Note that this is just a Sub where I've been testing out different components of the full macro. Any help on this error or what I'm doing wrong would be appreciated!
Sub Test()
Dim ws2 As Worksheet
Dim wb As Workbook
Dim LastRow As Long, LastColumn As Long
Dim LastRow2 As Long
Dim Name As Variant, SheetR As Variant
Set wb = ActiveWorkbook
Set ws2 = wb.Sheets("Comm")
LastRow2 = 6
'sort each sheet on date descending
With wb
SheetR = ws2.Range("A3:A" & (LastRow2 + 2))
For Each Name In SheetR
LastColumn = 0
LastRow = 0
With Worksheets(Name)
Worksheets(Name).Rows("1:1").AutoFilter
Worksheets(Name).AutoFilter.Sort.SortFields.Add Key:=Range("H1"), SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal
With Worksheets(Name).AutoFilter.Sort
.Header = xlYes
.MatchCase = False
.Orientation = xlTopToBottom
.SortMethod = xlPinYin
.Apply
End With
LastColumn = Worksheets(Name).Cells(1, Columns.Count).End(xlToLeft).Column
LastRow = Worksheets(Name).Cells(Rows.Count, 1).End(xlUp).Row
If LastRow = 1 Then
ElseIf LastRow = 2 Then
ElseIf LastRow = 3 Then
ElseIf LastRow = 4 Then
ElseIf LastRow > 4 Then
'The error is occurring at this next line
Worksheets(Name).Range(.Cells(2, LastColumn + 1)).Formula = "=F2"
Worksheets(Name).Range(.Cells(3, LastColumn + 1)).Formula = "=F3+O2"
Worksheets(Name).Range(.Cells(3, LastColumn + 1)).Select
Selection.AutoFill Destination:=Sheets(CStr(Name)).Range(.Cells(4, LastColumn + 1), .Cells(LastRow, LastColumn + 1)), Type:=xlFillDefault
Else
End If
End With
Next Name
End With
End Sub

Look at my annotation.
Sub Test()
Dim ws2 As Worksheet, wb As Workbook, LastRow As Long, LastColumn As Long, LastRow2 As Long, Name As Variant, SheetR As Variant
Set wb = ActiveWorkbook
Set ws2 = wb.Sheets("Comm")
LastRow2 = 6
'sort each sheet on date descending
SheetR = ws2.Range("A3:A" & (LastRow2 + 2))
For Each Name In SheetR
LastColumn = 0
LastRow = 0
With Worksheets(Name)
.Rows("1:1").AutoFilter
.AutoFilter.Sort.SortFields.Add Key:=.Range("H1"), SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal 'Added "." before the Key range
With .AutoFilter.Sort
.Header = xlYes
.MatchCase = False
.Orientation = xlTopToBottom
.SortMethod = xlPinYin
.Apply
End With
LastColumn = .Cells(1, .Columns.Count).End(xlToLeft).Column 'Added "." before Columns.Count
LastRow = .Cells(.Rows.Count, 1).End(xlUp).Row 'Added "." before Rows.Count
If LastRow = 1 Then
ElseIf LastRow = 2 Then
ElseIf LastRow = 3 Then
ElseIf LastRow = 4 Then
ElseIf LastRow > 4 Then
'The error is occurring at this next line
.Cells(2, LastColumn + 1).Formula = "=F2" 'Removed .range() as this is only a single cell being called
.Cells(3, LastColumn + 1)).Formula = "=F3+O2" 'Removed .range() as this is only a single cell being called
.Cells(3, LastColumn + 1)).Select 'Removed .range() as this is only a single cell being called
Selection.AutoFill Destination:=Sheets(CStr(Name)).Range(.Cells(4, LastColumn + 1), .Cells(LastRow, LastColumn + 1)), Type:=xlFillDefault 'Need to check your qualifiers in this line... using source, not destination
Else
End If
End With
Next Name
End Sub
Edit1: Fixed innapropriate call for range() on a single cell. Props to u/PeterT for calling it out

Answer 2

You've taken the time to build a With Worksheets(Name) ... End With block but failed to take advantage of it. Additionally, .Range(.Cells(...)) is bad syntax unless you provide two .Cells for a start and stop.
To rewrite your With Worksheets(Name) ... End With block,
...
With Worksheets(Name)
.Rows("1:1").AutoFilter
.AutoFilter.Sort.SortFields.Add Key:=.Range("H1"), SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal
With .AutoFilter.Sort
.Header = xlYes
.MatchCase = False
.Orientation = xlTopToBottom
.SortMethod = xlPinYin
.Apply
End With
LastColumn = .Cells(1, .Columns.Count).End(xlToLeft).Column
LastRow = .Cells(.Rows.Count, 1).End(xlUp).Row
If LastRow = 1 Then
ElseIf LastRow = 2 Then
ElseIf LastRow = 3 Then
ElseIf LastRow = 4 Then
ElseIf LastRow > 4 Then
'The error is occurring at this next line
.Cells(2, LastColumn + 1).Formula = "=F2"
.Cells(3, LastColumn + 1).Formula = "=F3+O2"
.Cells(3, LastColumn + 1).AutoFill Destination:=.Range(.Cells(4, LastColumn + 1), .Cells(LastRow, LastColumn + 1)), Type:=xlFillDefault
Else
End If
End With
