What is sb.append?
And why are you directing the DOC to return a false for the object
(unchecked)?
It's really difficult to diagnose your problem without code snippets that do
not include your API for which you are using to process this information.

Some codes like this:
------------------------------------------------------------------------
sb.append("<tr><td><input type=checkbox name=coking_data unchecked>Coking
Parameters</td>\n");
sb.append("<td><font face=arial size=1>Gas,Diluent</font></td></tr>\n");
sb.append("<tr><td><input type=checkbox name=reaction_data
unchecked>Reaction Parameters</td\n");
sb.append("<td><font face=arial
size=1>Temperature,Pressure</font></td></tr>\n");
sb.append("<tr><td><input type=checkbox name=decoking_data
unchecked>Decoking Parameters</td\n");
sb.append("<td><font face=arial size=1>Pressure</font></td></tr>\n");
--------------------------------------------------------------------------
if (sel[1]!=null && sel[1].equals("checked"))
...................................
Hope this will help.

It's been awhile since I've done JavaScript with checkboxes, but I seem to
remember that an unchecked box will return 0 (false).
