I am using the file downloaded from
http://www.contextures.com/excelfiles.html called DV0043 - Data Validation
Combobox With Entry Check. I copied and pasted the example code and created
the combo box but am having one issue. No mater what I select from the drop
down list, when I change fields I get the error message that what I selected
is not a valid value. I've traced the error message in the code but do not
understand why when I moved it to my spreadsheet I would get this error no
matter what I select.

CODE FOLLOWS:
Option Explicit
Dim strTargAdd As String

Private Sub TempCombo_Change()
strTargAdd = ActiveCell.Address
End Sub

Private Sub TempCombo_LostFocus()
Dim rngTarget As Range
Dim lDVType As Long
Dim strList As String
Dim rngList As Range
Dim wsLists As Worksheet
Dim lCount As Long
Dim strOldValue As String
On Error Resume Next

Set rngTarget = Range(strTargAdd)
strOldValue = rngTarget.Value
Set wsLists = Worksheets("Mileage")
lDVType = rngTarget.Validation.Type

***HERE IS WHERE THE ERROR COMES FROM***

If lDVType = 3 Then
strList = rngTarget.Validation.Formula1
rngList = wsLists.Range(Right(strList, Len(strList) - 1))
lCount = WorksheetFunction.CountIf(rngList, strOldValue)
If lCount 0 Then
' do nothing
Else
rngTarget.Value = ""
MsgBox strOldValue & " is not a valid entry for cell " & strTargAdd
End If
End If
End Sub

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As
Boolean)
Dim str As String
Dim cboTemp As OLEObject
Dim ws As Worksheet
Dim wsList As Worksheet
Set ws = ActiveSheet
Set wsList = Sheets("Mileage")
Cancel = True
Set cboTemp = ws.OLEObjects("TempCombo")
On Error Resume Next
With cboTemp
.ListFillRange = ""
.LinkedCell = ""
.Visible = False
End With
On Error GoTo errHandler
If Target.Validation.Type = 3 Then
Application.EnableEvents = False
str = Target.Validation.Formula1
str = Right(str, Len(str) - 1)
With cboTemp
.Visible = True
.Left = Target.Left
.Top = Target.Top
.Width = Target.Width + 15
.Height = Target.Height + 5
.ListFillRange = str
.LinkedCell = Target.Address
End With
cboTemp.Activate
End If

errHandler:
Application.EnableEvents = True
Exit Sub

End Sub

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim str As String
Dim cboTemp As OLEObject
Dim ws As Worksheet
Set ws = ActiveSheet

Application.EnableEvents = False
Application.ScreenUpdating = False

If Application.CutCopyMode Then
GoTo errHandler
End If

Set cboTemp = ws.OLEObjects("TempCombo")
On Error Resume Next
With cboTemp
.Top = 10
.Left = 10
.Width = 0
.ListFillRange = ""
.LinkedCell = ""
.Visible = False
.Value = ""
End With

errHandler:
Application.ScreenUpdating = True
Application.EnableEvents = True
Exit Sub

End Sub

I'd appreciate ANY assistance to resolve this problem
TIA!

There's an error in the code. This line:

rngList = wsLists.Range(Right(strList, Len(strList) - 1))

should start with Set:

Set rngList = wsLists.Range(Right(strList, Len(strList) - 1))

Thanks for pointing out the problem, and I've uploaded a revised version
of the workbook.
