[vba] Excel VBA Open a Folder

Using 2010 Excel VBA - I'm just trying to open a folder through a sub. What am I doing wrong here?

VBA

Sub openFolder()  
  Dim preFolder As String, theFolder As String, fullPath as String

    theFolder = Left(Range("T12").Value, 8)
    preFolder = Left(Range("T12").Value, 5) & "xxx"
    fullPath = "P:\Engineering\031 Electronic Job Folders\" & preFolder & "\" & theFolder

    Shell(theFolder, "P:\Engineering\031 Electronic Job Folders\" & preFolder, vbNormalFocus)

End Sub

I use this to open a workbook and then copy that workbook's data to the template.

Private Sub CommandButton24_Click()
Set Template = ActiveWorkbook
 With Application.FileDialog(msoFileDialogOpen)
    .InitialFileName = "I:\Group - Finance" ' Yu can select any folder you want
    .Filters.Clear
    .Title = "Your Title"
    If Not .Show Then
        MsgBox "No file selected.": Exit Sub
    End If
    Workbooks.OpenText .SelectedItems(1)

'The below is to copy the file into a new sheet in the workbook and paste those values in sheet 1

    Set myfile = ActiveWorkbook
    ActiveWorkbook.Sheets(1).Copy after:=ThisWorkbook.Sheets(1)
    myfile.Close
    Template.Activate
    ActiveSheet.Cells.Select
    Selection.Copy
    Sheets("Sheet1").Select
    Cells.Select
    ActiveSheet.Paste

End With
