Keep Getting an "object required" Error. Tried troubleshooting for a while to no avail. - recursion

Question

I keep receiving an object required error on line 32 for "oFileCollection" and am unsure if the cause of the problem is the function not receiving the information from the Case or if the function needs to have the whole argument and code inside of it in order to retrieve the information.
Option Explicit
Dim sDirectoryPath,Search_Days,iDaysOld,CmdArg_Object,lastModDate
Dim oFSO,oFolder,oFileCollection,oFile,oTF, SubFolder
'------------------------------------------------------
Set CmdArg_Object = Wscript.Arguments
Select Case (CmdArg_Object.Count)
Case 2
sDirectoryPath = CmdArg_Object.item(0)
Search_Days = CmdArg_Object.item(1)
Case Else
WScript.Echo "SearchFiles.vbs requires 2 parameters:" &_
vbcrlf & "1) Folder Path" &_
vbcrlf & "2) # Days to Search"
WScript.Quit
End Select
Set oFSO = CreateObject("Scripting.FileSystemObject")
iDaysOld=Date+(-1*Search_Days)
Set oTF = oFSO.CreateTextFile("C:\Old Files.txt")
WScript.Echo Now & " - Beginning " & Search_Days & " day search of " & sDirectoryPath
TraverseFolders oFSO.GetFolder(sDirectoryPath)
Set oFolder = oFSO.GetFolder(sDirectoryPath)
Set oFileCollection = oFolder.Files
Function TraverseFolders (FolderName)
Set SubFolder = oFileCollection
For Each SubFolder In FolderName.SubFolders
TraverseFolders (SubFolder)
Next
For Each oFile In SubFolder.Files
lastModDate = oFile.DateLastModified
If (lastModDate <= iDaysOld) Then
oTF.WriteLine (oFile.Path)
oTF.WriteLine (oFile.DateLastModified)
oTF.WriteLine ("-----------------------")
End If
Next
End Function
WScript.Echo "Now - Finished"

Here's my quite old example; posted as is unchanged…
Function ShowFolderListPlus analyzes supplied folder and calls itself recursively for all subfolders.
option explicit
Dim MyFolder, MyAgeLimitInDays, objFSO, numDateDiff, sResult
MyFolder = "C:\testC"
MyAgeLimitInDays = 365
sResult = ""
Set objFSO = CreateObject( "Scripting.FileSystemObject")
ShowFolderListPlus( MyFolder)
WScript.Echo "Testing files older/newer than " & Cstr( MyAgeLimitInDays) _
& " days:" & vbNewLine & sResult
WScript.Quit
Function ShowFolderListPlus( FolderToAnalyse)
Dim objFolder, itemFile, itemFldr, colFileList, colSubFldr, parFolder, sc, sa
sa = String( DepthOfPath( FolderToAnalyse), "-")
sc = FolderToAnalyse & " " & sa & vbNewLine
Set objFolder = objFSO.GetFolder( FolderToAnalyse)
Set colFileList = objFolder.Files
For Each itemFile in colFileList
If StrComp( Right( itemFile.name, 4), ".bat", vbTextCompare) = 0 Then
'exclude files of specified extension'
Else
numDateDiff = DateDiff("d", itemFile.DateCreated, now)
If numDateDiff > MyAgeLimitInDays Then
sc = sc & sa & "old "
'''-------------------------------'''
''' objFSO.DeleteFile( itemFile) ''' delete file older than limit
'''-------------------------------'''
Else
sc = sc & sa & "new "
End If
sc = sc & itemFile.name & " " & numDateDiff & vbNewLine
End If
Next
Set colSubFldr = objFolder.SubFolders
For Each itemFldr in colSubFldr
parFolder = FolderToAnalyse & "\" & itemFldr.name
ShowFolderListPlus( parFolder) 'calls the procedure itself recursively'
Next
sResult = sc & sResult
ShowFolderListPlus = sc
End Function
Function DepthOfPath( strPth)
Dim AuxArray
AuxArray = Split( strPth, "\", -1, vbTextCompare)
DepthOfPath = UBound( AuxArray)
End Function
Output sample:
