title: Checkbox not showing as checked
body: <p>The issue is I have a page with the following checboxes listed for a particular question.When I select one of the boxes and go to the next page and comeback then i find,none of the checkboxes appear to be checked.I have checked it on the back end and i was able to see that the checkboxes were indeed checked,but i was not able to view them as checked.I am not able to figure out as to why they dont appear to be checked.Any help regarding this would be appreciated.Thanks in Advance. The following is the code which i have in that page.</p>
  
  <pre><code> &lt;td&gt;
    &lt;input type="checkbox" name="test_na" value="N/A" &lt;?=$test_na?&gt; id="test_na"&gt;
    &lt;label for="test_na"&gt;NA&lt;/label&gt;
   &lt;/td&gt;
   &lt;td&gt;
     &lt;input type="checkbox" name="test_y" value="Y" &lt;?=$test_y?&gt; id="test_y"&gt; 
      &lt;label for="test_y"&gt;Yes&lt;/label&gt;
   &lt;/td&gt;
  
  &lt;td&gt;
   &lt;input type="checkbox" name="test_n" value="N" &lt;?=$test_n?&gt; id="test_n"&gt;
   &lt;label for="test_n"&gt;No&lt;/label&gt;
  &lt;/td&gt;
