Macro Help: Open All Drawings In Folder and Save As PDF

I have created a macro (thanks to finding code from one of Deepak's macros combined with one of mine) that is supposed to do the following;

-Open a Folder Selection Box (where the user selects a folder)

-Open all the drawing files in the selected folder (one by one, one after the other)

-Check to see if there is a folder called "PDF" in the directory, if not then create one

-Save the open drawing file as a pdf, building the save as name from custom properties in the referenced model

-Close the drawing

-Move on to next one

Now in my code below (and I have attached the macro file because there is the browse folder module attached) the macro will complete one drawing, close the drawing and show the msgbox if that "PDF" folder exists, if the folder does not exist it will create the folder, save the open drawing, close the drawing and fail on "sFileName = Dir"

If I comment out the "If Dir(PDFpath, vbDirectory) = "" Then MkDir PDFpath" and make "pdfpath=currpath" it runs perfectly and saves the drawings all in the selected directory.

Can anyone please help me solve this, so it creates that PDF folder and saves the PDFs in to it??
