[impin]

 <form action="savesalary.php" method="post">

<table width=100% border=0 bordercolor="#CC6633">

<tr>
						<tr>
                        <td>Employee Id: </td>
                        
     	  <?php
		  $empid=$_GET['id'];
		  
                            print"<td><input type='text' name='empid' value='$empid'></td>";
							?>
							
                        
                        </tr>

                        <tr>
                        <td>No of Days in Month: </td>
                        <td>
     	  
                            <input type='text' name='ndm'>
							
                        </td>
                        </tr>
                         <tr>
                        <td>No of Days Present: </td>
                        <td>
     	  
                            <input type='text' name='ndp'>
							
                        </td>
                        </tr>
                         <tr>
                        <td>Week Offs: </td>
                        <td>

                        </tr>
                         <tr>
                        <td>Additions: </td>
                        <td>

                        </td>
                        </tr>
                         <tr>
                        <td>Deductions: </td>
                        <td>
     	  
                            <input type='text' name='ded'>
							
                        </td>
                        </tr>
                      

<tr>
<td colspan="2" align="center"><input type="submit" name="submit" value="Send"></td>
</tr>

this is my savesalary.php

<?php
include("config.php");
$empid=$_POST['empid'];
$query="SELECT * FROM employee WHERE empid='$empid'";
$result=mysql_query($query);
$num=mysql_numrows($result);
$i=0;
while ($i < $num)
{
   $fsal = mysql_result($result, $i,"fsal");
    $i++;
}


$empid=$_POST['empid'];
$ndm=$_POST['ndm'];
$ndp = $_POST['ndp'];
$woffs= $_POST['woffs']; 
$add = $_POST['add'];
$ded = $_POST['ded'];
$month = date ("M-Y");

$tdaysp = ($ndp)+($woffs);
$ds = ($fsal/$ndm);
$t = ($ds)* ($tdaysp);
$total = ($t)+($add)-($ded);
$sal= round($total);

$query1 = "insert into salary (empid, ndm, ndp, woffs, add, ded, month, total) 
values ('$empid', '$ndm' ,'$ndp','$woffs' ,'$add','$ded','$month','$sal')";
mysql_query($query1);

//print "Data Updated Sucessfully";
?>

the data is not storing into the salary table... why?

READ FIRST: Turn On PHP Debugging Messages

Try that. Right now your code is completely ignoring the result of the query. You need to print the error if you want to debug it.
