Can't follow you. Post a screenshot of what you've got so someone can understand what you're trying to do. State what version of Illustrator you are using.
A "vector object" can be many things. Clipping masks don't "divide" anything, least of all raster images. They merely mask portions of their content. There is no clipping mask tool per se.
Unfortunately I can't post a screen shot, the work I'm doing is part of a research project into computer based art being run by a professor who's hired me to help him figure things out
I'm using CS 3, but can get access to CS4 if that would work better for what I'm trying to do. If clipping masks don't actually cut anything then maybe I need to look into another command, is there a command that will cut a raster obect using vector lines?
This is not something you want to do n Illustrator, i think there is a plug in for photoshop that does this though I am not certain.

No. Illustrator cannot cut (crop) raster images. Some employ the hideous workaround of setting the transparency mode of a clipping path to something other than Normal, and then flattening the transparency. But that actually re-rasterizes the selection, often with unpredictable and undesirable results.
Understand: Raster images are always rectangular arrays of pixels. You can't really cut them into other shapes.
I'm still just guessing at what you are trying to do. If you are trying to make something like a "jigsaw puzzle," you can simply contain copies of the same raster image (or Symbols Instances of same) in multiple clipping paths:
Thanks for the detail, JET ,a jigsaw puzzle is a very good way of describing what i'm trying to do, the only other question I have is whether or not this will create a large file size because of the duplicate images, (there are about 200 parts to this puzzle)
I don't know. You haven't provided enough information. I have no idea how large your raster image is, neither in scale nor in file size. I have no idea where you're going with this. Web? Print? Flash? You'll just have to try it and see.
At any rate, before you start, store the embedded image as a Symbol and use Symbol Instances on the page. Symbols are stored in the document file only once. See online Help. But there may be other size/space-related issues depending on the specifics.
Thanks very much JET that was quite helpful.
