If your query returns more than or less than one row of data, you will have
an error because the HTML will be invalid. Open the page in a browser,
right click and view the source code, then post it here so I can see what
your server-side code is outputting.
As an aside, you have an errant comma at the end of this line:
['Semester 12', <?php echo $row[12] ?> ], <-- this comma
which will cause IE to throw a tantrum like a petulant two-year-old child
(IE does not like commas after the last item in an array). Remove the
comma so IE won't complain.
