Newbie Trying to save a file from Graphic Converter

Hi,
I tried to write my first script today, after coming from programming appleScript was a bit of a difference. Anyway here is my problem I have a file that I would like to save, so I set up my path and then try to use the following line to get me a “pointer” to the file,

set the_save to open for access file fileSaveTemp as alias with write permission

afterwards I use a save window 1 in the_save to perform the save

the fileSaveTemp does not exist and I am under the impression that open for access will create it, is this the case?? Anyway, I get an error in the open for access line telling me that Access it not allowed to that file, I dont think this is a permissions issue as I am administrator and the disk has ownership turned off. I am not sure if this is the correct way to go about saving a new file, I couldnt find any examples, thanks for any assistance you may be able to provide
