here code working after installing new wamp server in new mini compaq laptop? errors:

$sno=mysql_result($result,$m,"sno"); $name=mysql_resul($result,$m,"name"); $location=mysql_result($result,$m,"location"); $sector=mysql_result($result,$m,"sector"); $status=mysql_result($result,$m,"status");*/?> <table width="320" border="0"cellspacing="0">   <tr>     <strong>   <td width="194"><strong><span class="style16"><font face="lucida console, lucida sans unicode">pv no:</font></span></strong></td>     <td width="110" nowrap><span class="style16"><strong><?php echo "$_post[pvno]";?></strong></span></td></strong>  </tr>    <tr>     <td width="194"><span class="style16"><strong><font face="lucida console, lucida sans unicode">sno</font></strong></span></td>     <td width="110" nowrap><span class="style16"><?php echo ''.$sno.''; ?></span></td>   </tr>   <tr>     <td><span class="style16"><strong><font face="lucida console, lucida sans unicode">project name </font></strong></span></td>     <td nowrap><span class="style16"><strong><?php echo $name;?></strong></span></td>   </tr>   <tr>     <td><span class="style16"><strong>sector</strong></span></td>     <td nowrap><span class="style16"><?php echo $sector;?></span></td>   </tr>   <tr>     <td><span class="style16"><strong>contractor</strong></span></td>     <td nowrap><span class="style16"><?php echo $contractor;?></span></td>   </tr>     <tr>     <td><span class="style16"><strong>contacts</strong></span></td>     <td nowrap><span class="style16"><?php echo $contact;?></span></td>   </tr>   <tr>     <td><span class="style16"><strong>location</strong></span></td>     <td nowrap><span class="style16"><?php echo $location;?></span></td>   </tr>   <tr>     <td><span class="style16"><strong>status</strong></span></td>     <td nowrap><span class="style16"><?php echo $status; ?></span></td>   </tr> </table>

the output error due is:

pv no:  agri008 sno      notice: undefined variable: sno in c:\wamp\www\cdf\new pro\pvsearch.php on line 162 project name     notice: undefined variable: name in c:\wamp\www\cdf\new pro\pvsearch.php on line 166 sector   notice: undefined variable: sector in c:\wamp\www\cdf\new pro\pvsearch.php on line 170 contractor   notice: undefined variable: contractor in c:\wamp\www\cdf\new pro\pvsearch.php on line 174 contacts     notice: undefined variable: contact in c:\wamp\www\cdf\new pro\pvsearch.php on line 178 location     notice: undefined variable: location in c:\wamp\www\cdf\new pro\pvsearch.php on line 182 status   notice: undefined variable: status in c:\wamp\www\cdf\new pro\pvsearch.php on line 186

any please appreciated enter code here

<?php echo "$_post[pvno]";?>

pvno not within quotes, treated constant, constant doesn't exists (thats notice tries tell you)

use instead

<?php echo $_post['pvno'];?>

there no reason double quotes around variable.

additional

<?php echo ''.$sno.''; ?>

quotes useless here to

<?php echo $sno; ?>
