Code/form Tweak On View Directory

I have a form from one of the gurus on site and I have tried to tweak the code to show a directory per record (Access2000) Its half working I open up the form and get "13- type mismatch"

vDir seems to be empty (I have pt a file in their to veiw)
running the cursor over QteNo & qteinsnme - both have what I expect in them (A number and a name respectively)
howver Vir seems to be empty and when i debug it oes straight to "Resume Exit_FilesAndDetails) second from bottom line of code copy code below

Private Function FilesAndDetails()
On Error GoTo Err_FilesAndDetails

Dim rs As Recordset
Dim vDir As Variant
Dim sPath As Variant

sPath = "C:Coverex international" & "Forms!main!QteNo" & " " & "Forms!main!QteInsnme" & " "

'Const sPath = "C:Coverex international(Me!QteNo)(Me!QteInsnme) """
' Const sPath = "C: emp" 'sPath must end with a back slash, sPath = "C:Windows"
CurrentDb.Execute "Delete tTempFiles.* from tFiles;"

Set rs = CurrentDb.OpenRecordset("tFiles")

vDir = Dir(sPath & "*.*")
Do Until vDir = ""
rs.AddNew
rs!FilePathName = sPath & vDir
rs!FilePath = sPath
rs!FileName = vDir
rs!ModifiedDate = FileDateTime(sPath & vDir)
rs!FileSize = FileLen(sPath & vDir)
rs.Update
vDir = Dir
Loop

rs.Close
Set rs = Nothing
