When anything produces unexpected results it's usually helpful to check
"the result" immediately after, e.g.:
set the defaultFolder to lessonsPath
if the result is not empty then
answer "Couldn't set folder: "& the result &"("& sysError() &")" \
&cr& lessonsPath
exit to top
end if
Things can go wrong in many placed, but file I/O is one of those areas
where error-checking can be an especially useful habit.
The sysError function will let you know what the OS is trying to tell
you about why it didn't work.
Also, it may just be a typo when pasting into email but there's a tab
character in "put" in the last line.
