Modify a script help?

Question

I have main AI documents that are named by a number (for example "320").  Within these master documents I have 50 different artboards also named by numbers (for example "14").  Muppet Mark created an amazing script for me that we use every day here.  The script exports each artboard as a separate PDF file (ai file really) and creates a concatenated file name of [master file name] + "-" + [artboard name] + ".pdf".   So my exported files look like 320-14.pdf, using the above number examples. 
I would like to modify this code (for another script/use) to export the same way, except leave off the...[master file name] + "-" +....part.  I'd like to have the resulting files be named only by the artboard name, and not including the master file name.  Using the same example, the new resulting file would have been named "14.pdf"
Mark - can you or anyone else advise on which line/lines of code need to be removed and/or changed?
Thanks!
Tim

Looks like I chopped a needed line out too… Ooops I'll check it this time… OK this does what you asked at this end…
