excel VBA runtime error - 1004 - vba

Question

I'm just trying to do something very simple with Vlookup, but am getting the 1004 error. Would really, really appreciate your help. Thanks in advance. Here's my code:
Sub test()
Dim user As String
Dim drawn As String
Set Sheet = ActiveWorkbook.Sheets("consolidated")
For i = 2 To 2092
user = CStr(Cells(i, 1).Value)
Set Sheet = ActiveWorkbook.Sheets("sections")
drawn = CStr(Application.WorksheetFunction.VLookup(user, Sheet.Range("A2:B3865"), 2))
Set Sheet = ActiveWorkbook.Sheets("consolidated")
Cells(i, 10).Value = drawn
Next i
End Sub

When you use VLOOKUP as a member of WorksheetFunction, an error will result in a runtime error. When you use VLOOKUP as a member of Application, an error will result in a return value that's an error, which may or may not result in a runtime error. I have no idea why MS set it up this way.
If you use WorksheetFunction, you should trap the error. If you use Application, you should use a Variant variable and test for IsError. Here are a couple of examples.
Sub VlookupWF()
Dim sUser As String
Dim sDrawn As String
Dim shSec As Worksheet
Dim shCon As Worksheet
Dim i As Long
Set shSec = ActiveWorkbook.Worksheets("sections")
Set shCon = ActiveWorkbook.Worksheets("consolidated")
For i = 2 To 2092
sUser = shCon.Cells(i, 1).Value
'initialize sDrawn
sDrawn = vbNullString
'trap the error when using worksheetfunction
On Error Resume Next
sDrawn = Application.WorksheetFunction.VLookup(sUser, shSec.Range("A2:B3865"), 2, False)
On Error GoTo 0
'see if sdrawn is still the initialized value
If Len(sDrawn) = 0 Then
sDrawn = "Not Found"
End If
shCon.Cells(i, 10).Value = sDrawn
Next i
End Sub
Sub VlookupApp()
Dim sUser As String
Dim vDrawn As Variant 'this can be a String or an Error
Dim shSec As Worksheet
Dim shCon As Worksheet
Dim i As Long
Set shSec = ActiveWorkbook.Worksheets("sections")
Set shCon = ActiveWorkbook.Worksheets("consolidated")
For i = 2 To 2092
sUser = shCon.Cells(i, 1).Value
vDrawn = Application.VLookup(sUser, shSec.Range("A2:B3865"), 2, False)
'see if vDrawn is an error
If IsError(vDrawn) Then
vDrawn = "Not Found"
End If
shCon.Cells(i, 10).Value = vDrawn
Next i
End Sub
