Klasse, MuffinMan, habe es hinbekommen.
Mein Code sieht nun so aus:
function ff_amount_validation(element, message)
{
    ff_pss_calculate();
    if (element.value==0) {
        ff_validationFocus('anzBasic');
        return message;
    } // if
    return '';
} // ff_amount_validation

function ff_pss_calculate()
{
    var amount = 0;
    var order;

    order = ff_getElementByName('anzBasic').value;
    if (order != '') amount += parseInt(order) * 10.17;

    order = ff_getElementByName('anzBasic2').value;
    if (order != '') amount += parseInt(order) * 19.17;
//  WIRD BEIDES KORREKT ZUSAMMENGERECHNET, auch Nachkommastellen!  //

    var result = Number( (amount*100)/100 );
    ff_getElementByName('amount').value = result.toFixed(2);

} // ff_pss_calculate

Warum das amount mal 100 und dann wieder durch 100: k.A., auf jeden Fall ist das Ergebnis sonst nicht 29.34 sondern 0,29 ...
var result = Number( (amount*100)/100 );

Auf jeden Fall kann man damit 2 Beträge zusammenrechnen, die auch hinter dem "Komma" korrekt sind. Auch wenn es nicht ganz kaufmännisch OK ist (1234.00 statt 1.234,00)...

Vielen Dank nochmals! B)
