Hi Nicole, in the test3 file, you have not made the change that I think is the main issue that I mentioned in the last post. Change line 35 from
$opts = {%$cell};
to
$opts = {@$cell};
After making that change, the problem will render.
For me at least, using the soon-to-be-released version 2.20 of WeBWorK, at this point I see tons of PG warnings that say "Table text must be in cells", which indicate that your string for the table is not using [. and .] surrounding some sort of content within the table.
