I'm glad to see that I wasn't the only one who was puzzle by the lack of a closing <td> tag here:
PHP Code:
<div class="smallfont">It is necessary to fill the railing by using 9 given symbols (Generally figures from 1 to 9, or letters indicated at the foot of the railing). Necessarily only once (but no more) on every line, column and region (or squared by 3 x 3).</div>
Now, I guess my new question is where is the location of the opening </tbody> tag?
