It's something else.

There are two radio buttons with the name, RKoptekst. When you reference
that name, as in form.RKoptekst, a collection is returned which contains
all elements in 'form' with the name 'RKoptekst', not the currently
selected button in that group.

To find the currently selected button, and its value, you can use
something like:

function findSelected( group ) {
var size = group.length;
for( var i = 0; i < size; ++i ) {
if( group[ i ].checked ) return i;
}
}

function bericht( form ) {
alert( form.RKoptekst[ findSelected( form.RKoptekst )].value );
alert( form.TKoptekst. value );
}

Hope that helps,
Mike
