@Sef McCullough – thanks, no pressure! 

There are many scripters here who I believe can also help...

@Calvin21914323wi10 – Untested, but perhaps:

var f = new Folder(myDocument.path+"/"+theResult.join("X"));

Or:

var f = new Folder(myDocument.path+"\\"+theResult.join("X"));

@Calvin21914323wi10 - Thanks for the feedback, please mark my previous reply as the correct answer. I would have thought that both versions would have resulted in a valid directory separator being added.
