[LON-CAPA-users] Panic - dropboxes not appearing?

Well, school started today, so of course things are immediately breaking
for me.

I have a problem that requests an answer code from a student. When that
code is correct, a block condition allows another problem part to be shown.
The second part asks them to submit an excel spreadsheet for grading (using
a dropbox).

Suddenly today, the dropbox portion that asks for the excel spreadsheet
shows the text for that part, and the stuff that indicates

 Submit entries below as answer to receive credit
 Save entries below as a draft answer (not submitting them for credit yet)

But no Dropbox area! No ability to send the filename!

Hitting Submit Answer doesn't seem to do anything.

I created a small test problem with a dropbox, and it does the same thing -
shows the text, gives the submission options, but no area for actually
submitting the file.



Code:  Main problem


<import id="11"> /res/monroe/brewington/Common/AnswerCode.library </import>

<script type="loncapa/perl">

$spreadsheet = "LabPractice.xls";
$user =&EXT("user.name");
$answerCode =&CalcAnswerCode ($spreadsheet,$user);

<import id="SpreadsheetInfo">
/res/monroe/brewington/Common/ExcelLabUtilityRef.library </import>


Code: library routine ExcelLabUtilityRef.library

<part id="Spreadsheetdone">
