Talkupation: dgkindy is on a distinguished road
I have three states as an option;

1: Null (default value of new record)
2: Not selected
3: Selected

When a new record is created, a ? would be desplayed indicating that the user has not indicated whether or not they are interesting in the item or not.

When they go to make a selection and save the settings, the recordset is then updated with either a 1 or 2.

Having problems getting this figured out.

Update record set:
PHP Code:
  if(isset($_POST["esod"])){
   if    ($_POST["esod"]==2) $sql.='esod=2, ';
   elseif($_POST["esod"]==1) $sql.='esod=1, ';
  } 
Create form:
PHP Code:
     if(empty($row['esod'])) $str_edit.='<td><input type="checkbox" name="esod" value="2" tabindex="'.$tabindex++.'"></td>';
     else     $str_edit.='<td><input type="checkbox" name="esod" value="1" tabindex="'.$tabindex++.'" checked ></td>'; 
Desplay:
PHP Code:
   if    (IS_NULL($row['esod'])) $str_row.='<td>?</td>';
   elseif(($row['esod'])==1)  $str_row.='<td><img src="images/ok.gif"></td>';
   else       $str_row.='<td></td>'; 

Entire code:
