Question

When someone selects a service number, then it will pop down and only give the total one records. I want it to give to total from two tables..

<?php

   $qry = mysql_query ("SELECT SUM(fruit) AS total FROM fruitinventory WHERE `fruitcolor` LIKE '%{$_POST['select']}%'");

$row2 = mysql_fetch_assoc($qry);


    echo $row['total'];

?>

<?php

   $qry = mysql_query ("SELECT SUM(fruitsmart) AS total FROM fruitrotten WHERE `fruitcolor` LIKE '%{$_POST['select']}%'");

$row = mysql_fetch_assoc($qry);


    echo $row['total'];

?>

Then

I want the total of both rows to display then too.

<?php 

$total return = $row+$row2 

?>

You can consolidate your two database calls into a single query, and use the columns of the result as your variables to echo out:

<?php
    $input = mysql_real_escape_string($_POST['select']);
    $sql = "
        SELECT
            (
                SELECT SUM(fruit) 
                FROM fruitinventory 
                WHERE fruitcolor LIKE '%$input%'
            ) AS totalfruit,
            (
                SELECT SUM(fruitsmart) 
                FROM fruitrotten 
                WHERE fruitcolor LIKE '%$input%'
            ) AS totalfruitsmart";
    $qry = mysql_query($sql);
    $row = mysql_fetch_assoc($qry);

    echo $row['totalfruit'] . '<br />';
    echo $row['totalfruitsmart'] . '<br />';
    echo $row['totalfruit'] + $row['totalfruitsmart'];
?>

Please, at the very minimum, use mysql_real_escape_string() to help prevent against SQL injection attacks which is what your original code was wide open to.
