  <tr> 
    <td style=color:blue width='139' height='26'><div align='left'><strong>$titl</strong></dv></td>
    <td style=color:blue width='80'><div align='center'><strong>$start</strong></dv></td>
    <td style=color:blue width='94'><div align='center'><strong>$end</strong></dv></td>
    <td style=color:blue width='91'><div align='center'><strong>$actual</strong></dv></td>";
   
print "<td style=color:blue width='74'><div align='center'> <SELECT NAME='title'>";
               
                    print "<OPTION VALUE='".$row["complete"]."'>".$row["complete"]." </OPTION> ";

                print "</SELECT></dv></td>";

echo" <td style=color:blue width='237'><div align='left'><strong>$remark</strong></dv></td>
<td style=color:blue width='60'><input type='submit' name='Submit' value='Submit' /></td>
  </tr> ";  [/code]

this is only for one condition i have more condition but when i click the edit button it change the column complete as a text field but i want only that row in which user click the edit button.
