    I wanna return value $sum (when $naklad > 800) to use in another function [ function calc_all($sum) ]

    Does somebody have idea.

    <?php
$rozmery = $_POST['rozmery'];
$rozm_textx = $_POST['rozm_textx'];
$rozm_texty = $_POST['rozm_texty'];

$naklad = $_POST['naklad'];
$pocetdruhov = $_POST['pocetdruhov'];
$lomy = $_POST['lomy'];
$laminacia = $_POST['laminacia'];
$parcialnylak = $_POST['parcialnylak'];
$mail_to = $_POST['mail_to'];

/*$rozmfix = $rozmery ;
$rozmvar = echo "ine rozmery: ".$rozm_textx." x ".$rozm_texty."<br />";
*/
if ($rozmery == "iny") {
    $x_rozm_text = $rozm_textx;
    $y_rozm_text = $rozm_texty;
    
    $vs_rozmery = "Iné rozmery (SxV): ".$x_rozm_text." x ".$y_rozm_text;    

echo "Rozmery: ".$vs_rozmery."<br />";        

}
else {
    $vs_rozmery = $rozmery;
echo "Rozmery: ".$vs_rozmery."<br />";
}
/*echo "Rozmery: ".$rozmery ."  Iné rozmery (SxV): ".$rozm_textx." x ".$rozm_texty."<br />";
*/

calc_rozmery($vs_rozmery,$naklad);



function calc_rozmery($vs_rozmery,$naklad){
    if ($vs_rozmery== 1){
        if ($naklad<=10){

    Hi,
    Can't get the detail. when you want to return why not use the return statement. if you can shed more details, it would be fine.

    regards,
    d_s

    I tried a code. i have question:
    why cant I send to the function input values?

    example:
    </head>

<body>
<form action="return.php" method="post">
X:<input name="x" type="text" /><br />

Y:<input name="y" type="text" /><br />

<input name="submit" type="submit" value="ok" />

</form>

</body>
</html>
    HTML:
    <?php
$x = $_POST['x'];
$y = $_POST['y'];

function add($x,$y)
{
$total=$x+$y;

return $total;
}
add($x,$y);

/*echo "1 + 16 = " . add(2,16);
*/
?>
    PHP:

    You're sending them to the function, but you're not outputting them.

    Try:
    echo add($x, $y);
