Using PDFCreator in Word

[Brettjg]

I wonder if I'm on the right track here? I'm used to writing macros in Excel,
and know nothing about Word (and I do mean NUTH-ING). However, I need to be
able to run the following macro in an open Word document to save it as a PDF.
The code I've supplied below is what I use in Excel, but I've changed a
couple of things like Activesheet to Activedocument. That's about as far as I
can get without help.

I don't know what to substitute for "UsedRange", and it immediately debugs on
pdfjob As PDFCreator.clsPDFCreator

Rather than using an Inputbox to put in the path name, I want it to save the
document as the "same name as open document.pdf" (that's where myDoc comes in
below)

Can this code be modified to work, or is it miles away? It kinda looks close
to me.
Your help is greatly appreciated. Regards, Brett

' I just want it to be set as the
'current document name.pdf
