hallo
ich habe das jetzt mal soweit geschafft aber bekomme das noch nicht mit dem aktivieren hin

in meinem Formular sind 4 ratio buttons und zu jedem ratio sind mehrere imputfelder.
jetzt sollen die imput-felder nur aktiviert werden wenn der dazu gehörige ratio aktiviert ist.

hier mal mein form..

<form name="payout" method="post" action="">

<div class="form_de">
<input type="radio" value="ueb" name="austype">
