If the filename is really correct, then it would appear to be a
permissions problem. Do you have read permission on that file? Try
opening it in Notepad or some other program.
If that works, then I'd suggest that you actually don't have the
filename correct. (Windows does dumb things like displaying the file
"asp.csv.txt" as "asp.csv" by default.) If you use the
file.choose()
function to select the file, you'll get the right filename.
