I have been making a script with the help of the forums on this fantastic site, and have come a little bit stuck.
The idea of this script ideally is, I will save the script as a application and place it into a folder, what I need the script to be able to do, is to recognise where it is, and when the application is run, to ask for a filename, then create a folder called Originals and save the final pdf as the filename. As the script inserts each individual pdf into the multi page pdf and then closes that pdf, i then want that pdf to be moved into the folder Originals.
Where I am stuck is how to make the script realise where it is, as I have only got this to work by specifying the exact location. Secondly I am totally stuck getting the script to move the pdf file which has just been closed to move into the folder called Originals. Any help on this will be a lifesaver. The script is shown below, it does work in its current state, it is just the polishing off that I am having issues with.
If anyone recognises some of the script below, that is because as I said, this script was made using script from this site.

set target_name_entry to display dialog "Please enter the name of the merged pdf:" default answer "unspecified " with icon note buttons {"Cancel", "Continue..."} default button "Continue..." giving up after 30 --Asks imager to Input the name of the scan folder, and calls it "file_name_entry"
