Save copy of workbook as new xlsm, runtime error 1004 - vba

Question

I'm trying to save a copy of the workbook as a new .xlsm file via the following code:
SaveAs FileName:=StrPadHoofdDocument & "\Docs\" & "\n\" & ".xlsm", FileFormat:=xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False
I get the following error: "runtime error 1004: method of object SaveAs of object_Workbook failed"
I've read a lot of other topics with the same kind of problem but I just can't quite solve it. Hope you guys can help!
full code:
Sub motivatieFormOpmaken()
Const StBestand = "Stambestand.xlsm"
Const motivatie = "Template motivatieformulier opstapregeling.xlsx"
Dim wbMotivTemp As Workbook
Dim wsMotiv As Worksheet
Dim PathOnly, mot, FileOnly As String
Dim StrPadSourcenaam As String
Set wbMotivTemp = ThisWorkbook
Set wsMotiv = ActiveSheet
StrHoofdDocument = ActiveWorkbook.Name
StrPadHoofdDocument = ActiveWorkbook.Path
StrPadSourcenaam = StrPadHoofdDocument & "\" & c_SourceDump
If Not FileThere(StrPadSourcenaam) Then
MsgBox "Document " & StrPadSourcenaam & " is niet gevonden."
Exit Sub
End If
Application.ScreenUpdating = False
Workbooks.Open FileName:=StrPadSourcenaam

Change this part:
FileName:=StrPadHoofdDocument & "\Docs\" & "\n\" & ".xlsm",
With this:
FileName:=StrPadHoofdDocument & "\Docs\" & n & ".xlsm",
As you see, the problem is that you are using twice \\. Furthermore, n is a variable and it is passed as string. In future similar cases, print the problematic string and examine it closely, with code like this:
Debug.Print StrPadHoofdDocument & "\Docs\" & "\n\" & ".xlsm"
Debug.Print StrPadHoofdDocument & "\Docs\" & n & ".xlsm"
The errors would be visible then.
