Microsoft Visual Basic- compile error: can't find project or libra

Hi
I know there is alot of questions and answers regarding project and library
which I have read but I still get the same error.

I have the following code in my workbook when it first opens however when
someone who has an older version of excel trys to open the form I get the
above error.

Sub GetLibraryGUID()

Dim c As Byte
Dim myCheck As Long
Dim P As Boolean
Dim rng As Range
Dim i As Byte


c = ActiveWorkbook.VBProject.References.Count

On Error Resume Next
Dim Message, Title, Default, T As Single

If Active***.ProtectContents = True Then
P = True
Active***.Unprotect
Else
P = False
End If

Range(Cells(ActiveCell.Row, ActiveCell.Column), _
Cells(ActiveCell.Row + 3, ActiveCell.Column + 1)).Select

For Each rng In Selection.Cells
If Not IsEmpty(rng) Then
i = i + 1
End If
Next

Sheets("Sheet3").Select
Active***.Range("a1").Select
On Error Resume Next
ActiveCell.Value = "NAME :"
ActiveCell.Offset(1, 0).Value = "MAJOR :"
ActiveCell.Offset(2, 0).Value = "MINOR :"
ActiveCell.Offset(3, 0).Value = "GUID :"
ActiveCell.Offset(0, 1).Value = _
ActiveWorkbook.VBProject.References(T).Name
ActiveCell.Offset(1, 1).Value = _
ActiveWorkbook.VBProject.References.Item(T).Major
ActiveCell.Offset(2, 1).Value = _
ActiveWorkbook.VBProject.References.Item(T).Minor
ActiveCell.Offset(3, 1).Value = _
ActiveWorkbook.VBProject.References.Item(T).GUID

If P = True Then
Active***.Protect
End If


End Sub

It seems to have problems accessing Microsoft Outlook which is causing the
debug as the form is to be emailed when the button is clicked.

Any ideas what else I need to do to fix this problem.

Thanks
