tkeeg,
using MS Word may not be a good way to save the file, use notepad, you need to save as a plain text file.
Make sure the file is name.txt or name.bas (not name.bas.txt windows can do stupid things).
To load the script
Start the camera, use the print button to go into Alt mode, if you don't see the menu (depending how you start the camera) use Menu button to bring up the CHDK menu.
find the scripting / load file option and select the file (as you did).
Then, exit the menu (Menu button again).
At this point you are still in <Alt> mode, you should now see "Ultra Intervelometer" at the bottom of the screen.
Press Shutter to start, when you want to stop press Shutter again.
Hope this is clear, good luck
