HI Nick,
Thanks for your reply. Actually, if you got to my third question, you'd see that I did add "File myFile" in the preamble, but I got the "not in this scope" error and had to put it i the loop, as well. I left it out in the preamble to test the sketch and it wound up in the forum sketch.
Are you using an Arduino wireless SD shield successfully? Or are you working with SD without the Xbee? Thanks again.
