Question

I have a function to calculate some mathmatic, but it seems like it wont put into database...

Is there something i dont know or?

function overskud($odds, $indskud) {
    $overskud1 = $indskud * $odds;
    $overskud2 = $overskud1 - $indskud;
    echo "$overskud2";
}   
$overskud = overskud($odds, $indskud);
mysql_query("INSERT INTO ODDS_kupon (kamp,odds,indskud,overskud,resultat,af,dato_ar,dato_moned,dato_dag) VALUES ('$kamp', '$odds', '$indskud', '$overskud2', '0', '$profilid', '$datoar', '$datomoned', '$datodag')");

Answer 1

Your query uses the variable $overskud2, but you did not define it (it only exists inside the function). I suppose you meant $overskud.

And the function should return its result, not echo it (confused with shell scripting?).
