Code error - Saving CSV file asking to overwrite - vba

Question

My code gives me error from
If Dir(Pth, vbArchive) <> vbNullString Then
I havent been able to find the error - Can someone help me what is wrong with the code? Is it supposed to say USERPROFILE, or am i supposed to write something else?
Sub Opgave8()
Dim sh As Worksheet
Dim Pth As String
Application.ScreenUpdating = False
' Create default desktop path using windows user id
user_id = Environ$("USERPROFILE")
' Create full path
file_name$ = "\AdminExport.csv"
Pth = Environ$("USERPROFILE") & "\Desktop\" & FileName
Set sh = Sheets.Add
For i = 2 To 18288
If Left(Worksheets("Base").Cells(i, 12), 6) = "262015" Then
sh.Cells(i, 2) = Worksheets("Base").Cells(i, 4)
End If
Next i
sh.Move
If Dir(Pth, vbArchive) <> vbNullString Then
overwrite_question = MsgBox("File already exist, do you want to overwrite it?", vbYesNo)
End If
If overwrite_question = vbYes Then
With ActiveWorkbook
.SaveAs FileName:=Pth, FileFormat:=xlCSV
.Close False
End With
End If
Application.ScreenUpdating = True
End Sub
Function UniqueRandDigits(x As Long) As String
Dim i As Long
Dim n As Integer
Dim s As String
Do
n = Int(Rnd() * 10)
If InStr(s, n) = 0 Then
s = s & n
i = i + 1
End If
Loop Until i = x + 1
UniqueRandDigits = s
End Function

There are a few issues in your code. I don't understand why you are getting an error message, but if you fix your issues, you are in a better position of finding the main problem.
Put Option Explicit at the top. If you do that, you will not do mistakes like setting the variable file_name$ but reading from the variable FileName.
You are building a path with double backslashes. Perhaps not a big thing and it'll probably work. Add a Debug.Print Pth just before your troublesome If. Press Ctrl-G to show the debug pane and study the output. Does the printed file path exist?
Don't use vbNullString. Test with abc <> "" instead.
