MkDir VBA Help want to use a ../filename structure

When I was working in the workbook and initially input

MkDir "..\Submittal Packaged\BOM PDF"

the script executed without any issues and created the folder.

After saving the workbook and re-oppening it gives the folling Run time error 76: Path not found.

Nothing had changed since executed originally.

yes it is. Has not changed

Not sure I understand are you asking me to put the CurDir command into the VBA window?

Here is my whole code to help also.... thing is also I am on a network server that we have defined as the Y drive.

Public Sub CopyFile2()
    MkDir ("..\Submittal packaged\BOM PDF")
    Dim rng As Range
    Const strNewDir As String = "..\Submittal Packaged\BOM PDF\"
    
    For Each rng In Range("L9:L1042").SpecialCells(xlCellTypeVisible)
        If CBool(rng.Hyperlinks.Count) Then
            With rng.Hyperlinks(rng.Hyperlinks.Count)
                If CBool(InStr(.Address, Chr(92))) Then
                    If Dir(strNewDir & Replace(.Address, Chr(92), vbNullString, InStrRev(.Address, Chr(92)))) = "" Then
                        FileCopy .Address, _
                        strNewDir & Replace(.Address, Chr(92), vbNullString, InStrRev(.Address, Chr(92)))
                    Else
                        FileCopy .Address, _
                        strNewDir & rng.Row & "-" & Replace(.Address, Chr(92), vbNullString, InStrRev(.Address, Chr(92)))
                    End If
                Else
                    If Dir(strNewDir & .Address) = "" Then
                        FileCopy .Address, _
                        strNewDir & .Address
                    Else
                        FileCopy .Address, _
                        strNewDir & rng.Row & "-" & .Address
                    End If
                End If
            End With
        End If
    Next rng
End Sub
