very bad code... you should save all the numbers in $vars and then plus them but with PHP, not with MySQL...

and put your code between [CODE.][/.CODE] TAGS...

<?php
$allsql="SELECT SUM(Salesprofit)+SUM(Serviceprofit)+SUM(softwareprofit)+SUM(Airtelprofit) FROM billing,service,software,airtel";
$profitall=mysql_query($allsql) or die(mysql_error());
while($row=@mysql_fetch_array($profitall))
{
echo $row['SUM(Salesprofit)+SUM(Serviceprofit)+SUM(softwareprofit)+SUM(Airtelprofit)'];
}
mysql_close($con);

?>

how can i declare variables in php but i want to echo it in a page...

you cant declare variables, you can DEFINE variables, for example, if i use a lot of time an user, you should do:

define(USER,$user);
echo "Hello ".USER;

It would be a lot simpler to get the sums one by one and add it in PHP.
