  &lt;tr&gt;
    &lt;td width="3" height="1"&gt;&lt;/td&gt;

      &lt;td width="336" rowspan="11" valign="top"&gt;&lt;form id="form1" name="form1" method="post" action="reg_forminsert.php"&gt;
          &lt;input type="text" name="Username" /&gt;

          &lt;input type="text" name="Password" /&gt;
          &lt;br /&gt;
          &lt;input type="text" name="Confirmpass" /&gt;
          &lt;br /&gt;
          &lt;input type="text" name="Name" /&gt;
          &lt;br /&gt;
          &lt;input type="text" name="Comment" /&gt;
          &lt;input type="submit" name="Submit" value="Submit" /&gt;
          &lt;br /&gt;
      &lt;/form&gt;&lt;/td&gt;
    &lt;/tr&gt;
  &lt;tr&gt;
    &lt;td height="19"&gt;&lt;/td&gt;
      &lt;td valign="top"&gt;Username&lt;/td&gt;
    &lt;/tr&gt;
  &lt;tr&gt;
    &lt;td height="4"&gt;&lt;/td&gt;
      &lt;td&gt;&lt;/td&gt;
    &lt;/tr&gt;
  
  &lt;tr&gt;
    &lt;td height="19"&gt;&lt;/td&gt;
      &lt;td valign="top"&gt;Password&lt;/td&gt;
    &lt;/tr&gt;
  &lt;tr&gt;
    &lt;td height="4"&gt;&lt;/td&gt;
      &lt;td&gt;&lt;/td&gt;
    &lt;/tr&gt;
  
  
  
  &lt;tr&gt;
    &lt;td height="19"&gt;&lt;/td&gt;
      &lt;td valign="top"&gt;Confirm Password &lt;/td&gt;
    &lt;/tr&gt;
  &lt;tr&gt;
    &lt;td height="4"&gt;&lt;/td&gt;
      &lt;td&gt;&lt;/td&gt;
    &lt;/tr&gt;
  
  
  
  
  
  
  
  &lt;tr&gt;
    &lt;td height="19"&gt;&lt;/td&gt;
      &lt;td valign="top"&gt;Name&lt;/td&gt;
    &lt;/tr&gt;
  &lt;tr&gt;
    &lt;td height="2"&gt;&lt;/td&gt;
      &lt;td&gt;&lt;/td&gt;
    &lt;/tr&gt;
  
  &lt;tr&gt;
    &lt;td height="19"&gt;&lt;/td&gt;
      &lt;td valign="top"&gt;Comment&lt;/td&gt;
    &lt;/tr&gt;
  &lt;tr&gt;
    &lt;td height="2"&gt;&lt;/td&gt;
      &lt;td&gt;&lt;/td&gt;
    &lt;/tr&gt;
  
  &lt;tr&gt;
    &lt;td height="44"&gt;&lt;/td&gt;
      &lt;td&gt;&lt;/td&gt;
      &lt;td&gt;&lt;/td&gt;
    &lt;/tr&gt;
  
  
  
&lt;/table&gt;

reg_forminser.php

$con = mysql_connect(“localhost”,“root”,"");
if (!$con)
{
die('Could not connect: ’ . mysql_error());
}

mysql_select_db(“forum”, $con);
echo “connection successful”;

mysql_query(“INSERT INTO ‘forum’.‘reg_info’ (Username,Password,Comfirm_pass,Name,Comment)
VALUES (’$Username’, ‘$Password’, ‘$Confirmpass’, ‘$Name’, ‘$Comment’)”);

echo “Record Inserted”;
mysql_close($con);

Confirm_pass and $Confirmpass aren’t the same, but I don’t think that’d be the issue.
