Function not returning a value

Hello,

I'm trying a make an ilogic rule that converts our vault file structure to our company's file structure.
The issue I'm having is the function creates the correct string value, but when I try to return it shows up blank.

Rule below. Highlighted the areas giving me trouble.

Sub Main

	Dim filepath As String = ThisDoc.Path
	filepath = "C:\_Vault\Designs\Customers\Koppers\Galesburg, IL\22-7008M Sorter Upgrade Equipment\29-Upper Drag Chain\01-Catwalk\22-321127.ipt"
	filepath = filepath.Replace("C:\_IPI_Vault\Designs", "T:")
	
	Dim index As Integer
'	Dim folderpath As String
'	If filepath.Contains("A Level 2 customers")
'		index = GetNthIndex(filepath & "\", "\", 6)
'		folderpath = CreateFolderPath(filepath.Split("\"), Left(filepath, index), 6)
		
'	Else
'		index = GetNthIndex(filepath & "\", "\",5)
'		folderpath1 = CreateFolderPath(filepath.Split("\"), Left(filepath, index), 5)
'		MessageBox.Show(folderpath1)
'	End If
	
	index = GetNthIndex(filepath & "\", "\", 5)
	Dim folderpath As String
	folderpath = CreateFolderPath(filepath.Split("\"), Left(filepath, index), 5)
	MessageBox.Show(folderpath)


	
End Sub

Public Function GetNthIndex(searchString As String , charToFind As Char, n As Integer) As Integer
	Dim charIndexPair = searchString.Select(Function(c, i) New With {.Character = c, .Index = i }) _
	.Where(Function(x) x.Character = charToFind).ElementAtOrDefault(n - 1)

	Return If (charIndexPair IsNot Nothing, charIndexPair.Index, -1)
End Function

Public Function CreateFolderPath(folders As String(), folderpath As String, i As Integer)

'	MessageBox.Show(folderpath)
'	MessageBox.Show(folderpath)

	If IO.Directory.Exists(folderpath & "\Sub Jobs\" & folders(i))
		CreateFolderPath(folders, folderpath & "\Sub Jobs\" & folders(i), i + 1)
	Else
		MessageBox.Show(folderpath)
		Return folderpath
	End If
End Function

Hello @daltonNYAW9,

The function return object type is not specified :

Public Function CreateFolderPath(folders As String(), folderpath As String, i As Integer) as String

Kind regards,

FINET L.

Thanks for the quick reply! Yep it was a formatting error. I made the following changes in red.

Public Function CreateFolderPath(ByRef folders As String(), ByRef folderpath As String, ByRef i As Integer) As String

'	MessageBox.Show(folderpath)
'	MessageBox.Show(folderpath)

	If IO.Directory.Exists(folderpath & "\Sub Jobs\" & folders(i))
		folderpath = CreateFolderPath(folders, folderpath & "\Sub Jobs\" & folders(i), i + 1)
'		Exit Function
	Else
		MessageBox.Show(folderpath)
		
	End If
	Return folderpath
	
End Function
