Hi gurpreet ,
Got error because your html code does not meet the html code rules.
You have two columns in each <tr>, but in the code below you used two colspan="2". You should remove one <td> target of this <tr>
<tr bgcolor="#ff0000" unselectable="on">
<td style="height: 88px" valign="top" colspan="2">
<p> </p>
</td>
<td style="width: 803px" valign="top" colspan="2"></td>
</tr>
Regards,
Ken
