Upload pdf file, rename it and save it to specific folder

[Ellendigitl00]

Hello all,
I'm having some trouble with my VBA Userform: I want to upload a pdf file to my Userform, rename it and then save that pdf to a specific folder in my computer.

What I have is:

Private sub SaveButton_click()
'save file to PDF
Path = "directory"
FileName = Data.Value & "_" & Description.Value & "_" & ".pdf"

ExportAsFixedFormat Type:=xlTypePDF, _
FileName:=Path, _
OpenAfterPublish:=True

MsgBox ("Note: This file is now saved with the name of " & FileName & " in " & Path & ".")
End Sub

Private Sub Upload_file_Click()
Dim result As Variant
result = Application.GetOpenFilename("PDF Files (*.pdf), *.pdf")
End Sub

I think my problem is with the fuction ExportAsFixedFormat Type, because the Userform is trying to export something that doesn't exist in Workbook.... Does anybody know this?
Thanks in advance!
