Macro to Delete items where ageing in col M is less than or equal to 90

I have tried to write code below to delete all items in Col M where ageing is less than or equal to 90


I have highlighted the rows to be deleted

When running the macro, no rows are being deleted

It would be appreciated if someone could assist me

 Sub Delete_itemslessthan90()
Dim LR As Long, i As Long
Application.ScreenUpdating = False
Application.EnableEvents = False
For i = LR To 2 Step -1
With Sheets("Maturities")
LR = Cells(.Rows.Count, "A").End(xlUp).Row

If .Cells(i, 13).Value <= 90 Then
.Rows(i).EntireRow.Delete
 End If
End With
Next i
 Application.ScreenUpdating = True
 Application.EnableEvents = True
End Sub

I have managed to resolve issue, by amending my code as follows:

  Sub Delete_itemslessthan90()
Dim LR As Long, I As Long
 With Sheets("Maturities")
        
LR = .Cells(.Rows.Count, "A").End(xlUp).Row
For I = LR To 2 Step -1
If .Cells(I, 13) <= 90 Then
.Rows(I).Delete
End If
Next I
        End With

End Sub
