Hi,

if (radio.checked)

wozu diese Fallunterscheidung?

{                                da das| meine ich
              document.getElementById('pVMin'+radio.name.substring(5)).disabled = false;
              document.getElementById('pVMax'+radio.name.substring(5)).disabled = false;
          } else {
              document.getElementById('pVMin'+radio.name.substring(5)).disabled = false;
              document.getElementById('pVMax'+radio.name.substring(5)).disabled = false;
    }

Du machst in beiden Fällen dasselbe. Also kann man das ganze if-else-Konstrukt auf

document.getElementById('pVMin'+radio.name.substring(5)).disabled = false;
document.getElementById('pVMax'+radio.name.substring(5)).disabled = false;

reduzieren.

cu,
Andreas
