This is based on a flash Action Script tutorial from Flash Mx Studio. It took me fifteen minutes to type the code, but much longer to get it to work. My clerical skills are atrocious. My perception doesn't match what's on the page. It took me the longest time to catch the two typos: "=+" instead of "+=" and "_" instead of "._" (This is why I'm not an air traffic controller.) Any time I catch myself thinking This is hard! I can't do this. I tell myself to stop whining and keep at it.
