[LON-CAPA-users] Help with &EXT

[Todd Ruskell]

Hi all,

In a problem, I can do something like:
    &EXT('user.resource.resource.current.11.submission')
to get the submission text for a part.  We use this a lot in conditional
statements to open up more material only after *something* has been
submitted into an essay response box.

Our current challenge is that this doesn't appear to work if students upload
a file, instead.  We've tried
    &EXT('user.resource.resource.spdsht.upload.submission')
for a problem part called "spdsht", but the above always returns a null.  Is
there a different incantation we might use to, for instance, at least get
the name of the uploaded file, so we know when students should be allowed to
move on?  It's really hard, for instance, to have students enter a
spreadsheet without actually uploading the file.

Thanks in advance,
Todd
